The Lola is a T492, Sports 2000 but I've put a Porsche 911 engine in, 3200cc 11 years ago.
247 bhp and the car weighs 560 kg, used for hillclimbs which I've done for 30 years now.
At my age I should know better....
Google Lola T492 hillclimb and its the blue one!

Made some good progress over the last 2 days.
Cured the carb flooding issue. The carbs have a float with a brass tang in the centre which bears down on the needle valve. I found the angle was at 45 deg and not true to the needle valve causing a side load on the needle and jamming open, hence the flood of fuel.
Tick off the List.
Got the engine running better, far better with oh-so-small incremental movements of the tick over screw and the pilot air/fuel ratio screw, talk about a tight rope tuning. These carbs are infamous for this quirk.
Tick off the List.
Fixed the loose headlamp mountings by re-assembling the top fork handle bar yoke and all snugged-down nice and tight. No headlanp shakes now.
Tick off the List.
Trial and fitted the mega expensive side panels except they didn't fit at first. Numpty here had placed the tool box in the wrong pair of mounting holes in the chassis frame, what a faff to move and re-fit! All on now.
Tick off the List.
Fuel tank back on and fully coupled up. Pesky balance tube connecting the left and right sides of the tank fought me all the way, but lost.
Tick off the List.
Fitted the new seat from Taiwan, what a bargain for £100 delivered, resplendent with the 'HONDA' script of course. Perfect fit, fabulous.
Tick off the List.
Fitted the aluminium number plate at long last, really looks the Classic it is.
Nearly completed now, waiting for a new expensive starter chain to arrive and the bike can come down off the stand although it is very convenient on the stand while I prepare for some work on the Lola and the 911.
3 weeks late on the project!

I think you well know the classic bike world has many facets.
Buying a done AJS would be in the. Price range, maybe, a done Bantam is in range and possibly many others.
Not my aim though.
I like the rebuild journey, the fight to overcome issues like the current one, maybe frustrating for me and you/ others, but all prt of the enjoyment.
For the Money spent I could have a new Chinese AJS, single, fuel injected, disc brakes, all mod cons and a real looker, but....
I don't really like big old oily British bikes, though a Royal Enfield appeals.
I think all old bikes are cantankerous and awkward as are all classic cars, all of a different age and attitude, today all quirky and eccentric.
Oddly, those new AJS bikes have 1/2 the power of this Honda, and double the braking!

TRG:
Yes, this is the 2nd time round though!
Did the thinners route before taking the carbs for professional US clean, hoped it might loosen any debris.
Trying to get back to everything is actually clear today, so thinners and air again.
I'm now convinced the drillings and jets etc are all clear the ups and down cross drillings are all clear and there are 5 90 deg corners in the drillings and some very short runs, but all ok.
I have carb cleaner coming out of every port and fine hole aided by the 60 psi air jet.
Sympathy? Yep, could do with some, encouragement? yep need that too as success is in short supply, advice? always needed, every day is a school day.
I am not alone, there is a fellow Honda Twin owner having some carb probs also not far from me, but his probs are slightly different.
Given time I'll get this right, just need to stay in the trenches to avoid snipers and heavy artillery from the Salisbury direction!
Next report will be me bragging it is all ok.

« on: November 07, 2020, 12:34:44 PM »£100...tempting!
My count so far is £2760 for absolutely everything, so when done I could sell at a PROFIT!
Only ever been in that position once before in my tinkering life.
Plan is to remove the carbs and drown them in cellulose thinners and rig up an airline so to blast a laser sized air stream down the drillings to get the pilot jets to work sub 1800 rpm because they are doing nothing at present.
Bought some bling for the bike today to keep me going, the aluminium number plate has finally arrived!
Bike is definitely All Show, No go at present, bit like a little French bike was....

No, but a single carb bike would be good...
I'm missing something, but goodness knows what.
I'm sure mini has a solution esp as it's bonfire night everywhere.

The starter sounded terrible (electric) so replaced the motor, replaced the rollers/caps and springs, didn't replace the chain (mistake I think) and it sounds as awful now as it did before.
Parts were delayed as the 'in-stock' cover gasket was in fact in stock in the USA, but parts arrived today.
Putting that snag to one side, started the engine.
Would not start, churned over and over and then realised I had left the plug caps off....day not going well.
Running now but really not well. LH side hot, smoking rich and rusty water droplets profusely coming out the back, RH side cold. Here we go again!
Cold rh side carb then really flooded!.
Removed that carb and checked the float level, 21mm with the float just touching the sprung tip.
Decided to check the needle to the brass seat and that seals, so did a radical thing and set the float to 21 with the car upside down, ie the needle seated by the weight of the float.
Put it all back together and no flooding, however stone cold when running (LH side hot and smoking rich) and the speed adj screw does nothing, understandable as no combustion on the RH side...
It's 4.00 o'clock in the afternoon, just had a cup of tea and put the bike into the garage and tomorrow is another day.
Will this bike ever come into tune?

When my Terrot and the little BIMA were on ebay for sale I had several offers from Shop fitting companies wanting the bike for window displays which disheartened me.
The Terrot found a very enthusiastic owner with a big Gite in southern France which is where the bike now is.
The 'clientele' for the BIMA were a very different lot, from 'I want it for free, delivered' to 'give ya hundred quid mate' to nearly break-even sensible offers.
I took non, felt I was worth more.

Fabulous little bike and a great job done by the looks of it.
These light bikes are good diy projects esp if the 'journey' is where your interests are which is true in my case.
I find restoring/rebuilding bike really good, easy to do compared to classic cars.

Ha!
I'm WAY AHEAD of you all.
Have this already, it works, quite horrid to ride, thinking of electric motor instead of petrol and save this planet.

I think my next project is the hall stairs.....
The carbs could not be cleaner!
Brake cleaner shoots through all the passages and jets, and to top it off they spent time in the US cleaner at Villiers Services this morning.
Bike running on equal heat both sides and a low tickover. I don't trust the tacho's accuracy.
Good response to the twist grip so leaving it all at that.
The air screws STILL do nothing around the 0.5 turn to 2.5 turns to the tick over.
The starter chain/sprags etc make an awful din now but sometime hook up and spin the engine well to start, so taken the generator cover.case off.
The chain is very slack, but i doubt it would go on if I took a link out.
Are they supposed to look 'too slack'?
The lower half is nearly touching the engine case.
I have new sprags etc coming, but maybe I should bite the bullet and fit a new chain while in there.
Oil came out black, so discarded.
Last snag to fix is the leaking lh side fork.
Fork oil keeps on coming out albeit very slowly. Seems to be coming from where the front mudguard mounts. Maybe the fastener hole has broke into the lower fork casting?
Anyhow, still progressing.

Yes, I now have a doubt in my mind about the drillings thanks to John!
There is one that is about 8mm long, drilled and sealed by ball bearings right in the heart of the body for the air ratio pilot screw and I have to get that sorted now.
I've cleaned old Porsche weber carbs (huge things) in thinners soaked for a week and that seemed quite good but the drillings are far larger dia.
Plan is to strip them and take the bodies to Villiers Services close to me and get them to US clean as they would for their carb rebuild service, and, as you suggest a weekend in thinners will finish the job.
As an expert ow on French and Japanese carb stripping it won't take long. Practice makes perfect and this will be the 9th time the carbs have been apart....

Yes, take your point.
It is running, but maybe not at it's best!
There are 3 small drillings to the pilot. The long one from the pilot to the small hole just behind the slide is clear on both and easy to poke through (I'm using BOC gas welding tip cleaning wires).
However, there are two shorter ones that you cannot get to unless you remove the small ball bearing seals, and those could be blocked.
No idea how to clear them. Both carbs have been in a small US bath for hours before all this kicked-off.
Maybe a professional US bath is needed?

Thank you.
With this one coming to a close, I doubt I will get a chance to ride it anytime soon, so that may be 2021..
Not sure what to do for a project next. Hard to find a project of this type to consume time and give interest that is small enough to squeeze into the garage.
Pause for thoughts.
