Re: Changing to a 60mm crank

You may find that the 60mm crank will not fit in your casing, many of the 60mm cranks for sale at the moment have large conrod big ends. You may also find that the piston skirt bottoms out before BDC, as the 60mm crank will pull the piston 1mm closer. You can trim the piston skirt, but this will alo...

Was this under load, or open circuit. You'll find that most regulators need a load across them to pull the power through.

Re: Crank Advice Please

I generally mock it up with whatever gaskets and packers I have about to get the piston where I want it... then take them out and measure.. and then order the one to suit... Same goes with Gaskets at the top end to get the squish I need... Just finished building an engine for a mate ... 60 x 110 cra...

Re: Crank Advice Please

Either will do the job well... Longer rod gives a smoother setup. I have a 60 x 115 in one scoot and a 60 x 110 in the other, and to be honest I cant tell the difference.

The 115 crank through I used a lower crown height piston to avoid a large packer...

Worth downloading and keeping for future reference... Page 72 onwards deals with setting up your carb and what jets etc are at play and when.

Check the basics first too... have you got an airleak somewhere?

Re: Recommended gp chain tensioner

recently tried the GT tensioner, but the sliding bolts at the back caught on the casing, and couldnt loctite the main bolts in position at the beginning. But a good value piece of kit... Jockeys Boxenstop pull down tensioner has to be my favourite though; although if you are using a slightly longer ...
