British Bikes / Mystery gas tank
« on: October 27, 2018, 08:46:54 PM »
Greetings all. I purchased the attached gas tank at a swap meet AKA Auto Jumble, and I have no idea what model bike it came from. Please let me know if anybody can identify it. Thanks in advance, Steve

Bike will leak on the center stand as well.

Thanks one and all for the input. As stated, there is good return to the tank. Amount of oil coming out of breather is minimal but annoying. When sitting at idle it leaves a very small puddle. As for cam shaft breather, I checked the spring back on the cam when I had the cylinders off and it looked good. I guess I will ride it some more, but I have an interested party and I don't want to sell it like this. Steve

Well it's on to a different bike. The previous issue regarding the 1969 T100 was resolved when I found a piece of sludge sitting in the bottom of the crankcase drain plug. It was large enough to be drawn up and block off the intake scavenge return tube, causing the crankcase to fill up and blow out the breather. That was a first for me!
Now I have a similar problem but with a fresh rebuilt motor on a 1969 Triumph T120 Bonneville. Motor was completely gone through by a friend, (very qualified), who has passed on. My job was to get it running and sell it for his wife. Problem is oil is coming out the crankcase breather. I assumed "wet sumping" but did not have excess oil in crankcase. I pulled the top end to check rings and all was good. I re-honed and installed a set of rings and installed a new oil pump. Compression is good, I have good oil pressure and good return to the tank. I have put almost 50 miles on the bike. It runs great but continues to push oil out the breather. I have re-checked the sump and it's not over filling. Oil tank breather is clear as well. I am at a loss for what to do. Any thoughts? Steve

Interesting replies. The compression is low, actually 115lbs. per side. I just don't know if the low compression can cause oil to blow out the crankcase breather. Is there a definitive answer? Steve

What's coming out is a foamy white substance, something I would not like to put back into the engine. Thanks though.

I'm back regarding the 1969 Triumph T100 Tiger. As was mentioned in previous post, the bike blows considerable oil out the crankcase breather. I have since put some miles on it and it runs great, but continues to blow a lot of oil, both riding and at idle. NO smoke however. I do not know what to do next. Any helpful suggestions? Good oil return to the tank and top end is getting oil as well. Steve

Thanks for all the input.
 I did change all the fluids. There was very little oil in the sump.
I failed to mention in the earlier post that after the first ride the top end including the carburetor was extremely hot and I wonder if it's not oiling properly? Is there a good way to check? I can't help but think a good flushing out, maybe with Marvel Mystery Oil could help. Steve

Just fired up a 1969 Triumph T100 Tiger for the first time in years. I have no history on the engine or repairs etc. After a good tune and service the bike started right up. Rode it and everything seemed in order. Upon return home, after just a couple of miles, there was significant oil coming out of the crankcase breather. Is it advisable to flush out the lubrication system on these bikes prior to start up and if so what should one use? I was getting good oil return to the tank but I did not check the pressure. Any thoughts? Steve

The Classic Biker Bar / What sealer to use with copper gaskets
« on: August 30, 2017, 05:01:34 AM »
Building a Triumph T150 and thought I'd try copper gaskets on the rocker boxes and the base of the barrel. Question is what sealer to use? Do you apply "copper coat" like on the head gasket or a non hardening sealer like Three Bond? Appreciate any advise. Steve

Greetings
 I need to confirm whether the frame I have is a genuine Triumph GP race frame or just a Tiger 100c that could be set up with a race kit. Frame (rear section) is marked F1629. Please see attached pics. and your feedback would be appreciated. Steve

So is there a test I can do to determine if in fact it is a ring issue? Will a straight compression test tell me if ring gap is too large?
