Re: Re-torqueing after rebuild benefits?

Don't forget the flywheel. On every rebuilt I retorque the flywheel after I set the timing. Just the act of running after the first time will get the flywheel to settle enough it give it a small turn on the wrench.

Re: Progressive fork springs vs standard

As a general rule I try to avoid pot holes but hey to each their own right? I run progressive springs in all 3 of my road bikes (tv200, li190, rb20) and I also have dampners on the forks. Not quite sure what crashy means but I suspect you mean fork dive. PS will not eliminate that problem as you wan...

Re: series 1 fork links

I've seen grease zerts like that on a LD (mk3 125). I was told those were the origional zerts for the bike.

Re: Which piston...

Lol! 1000 miles. My last poverty thick ring piston did 8k before i decided to replace it.Where did the rebore after a 1000mls come from too? Ok 1k can be a bit on the short side (unless running a rapido, hole the piston or catch a ring). You have to admit 3 ring pistons are old technology and arn't...

Re: Which piston...

Just need to look at it this way. Is it cheaper to replace the piston and rebore the cylinder every 1000 odd miles because they skimped with a 3 thick ring circus piston or just pony up the coin and forget about it? I don't know about anyone else but I like to ride much more than I like to turn wren...

Re: Which piston...

Assuming 58/107 crank I have had nothing but good experience with the MBD RT piston. Have them in two bikes right now and have put a few motors for other together using them (Indian stage 4 and 2 rt top ends). They are expensive compared to others but quality always is.

Drive axle holding tool.

I'm not a dealer or shop but I am selling these because I believe they work and make the assembly job easier. This is a must have for pulling the drive axle in to it's bearing. No more kungfu GI Joe death grip on the axle. No more bloodied knuckles. No more damaged rear bearing! Throw your hammer aw...

Re: Can LI 125 Crank Be used in Jet 200?

Same taper, same stroke and same rod length so that part checks out.


Have the crank check for true and make sure it's cleaner than a clean thing before installing.

Re: How hot is too hot?

I know it sounds weird but running too rich can cause a hot condition with the motor. Get the jetting dialed in correctly, light coffee/cream colored plug and the engine will run cooler.
