British Bikes / Monobloc air filter
« on: February 14, 2010, 06:26:02 AM »

This should be an easy one...

I purchased a monobloc for my Triumph to replace the concentric that was on the bike.  How do I get the spin on air filter (the hole is centered) to fit?  The filter won't clear the carb without some sort of adapter.
Or do I need a different air filter?

Thanks.

British Bikes / voltage drop
« on: July 12, 2008, 10:56:04 AM »

I get a voltage drop from the battery when just turning on the ignition key.  With an older batter it can be around 3 v.  

Is this to be expected or do I have a "leak" somewhere?

The bike is a BSA A65 with stock electricals.

thanks,
GJM

British Bikes / Re: 1968 BSA Lightning ...its getting older !

Good luck.  I just started the same thing - same bike.

I'll be glad to trade any tips b/c I don't know that much about BSA's.

Curious as to the answers you get on oils - I'm in Texas also.

British Bikes / BSA STATIC TIMING
« on: September 12, 2007, 01:30:02 PM »
I'm working to get a 1968 Lightning with points running.  I don't have the special tool that locks into the flywheel to hold the engine at the right point to set advance timing.  I would use a degree wheel to accomplish that but don't know what degree setting to use.

The full advance setting is 34 deg btdc but I don't know if this is the place to set the engine for static timing.  (For Triumphs you take full advance and subtract 2 times the number stamped on back of the aau)

I will use a strobe once I get it going.

thanks.

Thanks

British Bikes / CD Manuals
« on: August 25, 2007, 02:59:05 PM »

Has anyone purchased any of the CD Manuals available?  Kim the CD Man has some advertised and they seem pretty good from the table of contents listed.  Any comments on these or any other ones?


Thanks ::)

British Bikes / Norton serial no
« on: August 06, 2007, 12:24:37 PM »
Does anybody know if the number stamped on the front of the fork yoke should match engine or frame numbers?

The bike is a Norton Atlas.


Thanks for any help

British Bikes / Norton gas tank & ethanol
« on: June 30, 2007, 02:56:49 PM »
My bike is a Commando w/ fibreglass tank.

I have found that the mogas / ethanol blend being used in the US is causing problems in my carbs - a fouling on the needles which I believe is some sort of resin being leached out of the tank.

After draining the tank and using 100 LL avgas - no problem.

Two questions:
1) Is there any problem using 100% avgas?
2) what is the best tank coating system to combat the ethanol?

thx

British Bikes / Norton carb needle fouling
« on: December 02, 2006, 12:37:46 PM »

I've had problems with the Amals on my 71 Commando and have solved most but this one.

I'm getting this fouling/varnish on the needles after very little run time.  (Also getting clogged pilot jets but these are easily cleaned with a guitar string.)  If I pull the needles and clean them the bike runs like a top, but this is alot of work for every time I want to ride.  

Any ideas what's causing this?

British Bikes / 1971 Commando carb problem
« on: August 21, 2006, 04:13:09 PM »

My 1971 Commando has always apparently run very lean. Even when warmed up, she has to be left partially choked. I changed the needle settings and this helped some.

Suddenly it became about impossible to start. I could use starting spray but it would run about 3 sec and then seemed to be starving for fule. I took the carbs apart and the only thing that looked wrong was the needles had some sort of fouling about 1/2 way up - it looked like carbon. I got the fouling off by gently rubbing with steel wool and she runs ok but still needs priming with either starting spray or squirting some gaso into the intake.

I am pretty sure all jets and passages are clear and the float setting is about spec.

The carbs are AMAL 930'2

The bike has a Boyer ign.

Any ideas??

British Bikes / Triumph numbers
« on: March 03, 2006, 12:30:06 PM »

Is there a difference between a T120 and a T120R?  The manuals seem to indicate that these are UK and US models, respectively.

 The bike is a 1966

Thx
