Valve adjustment procedures TRX 400 & 450 all

VMS · 11-29-2010, 04:52 PM

Hiya,

Looking to make this check/adjustment on a 2001 foreman 450s. From the diagrams, it only shows adjusting one valve. Do you adjust both to the same specs from TDC?

Also, how do I tell I am on a compression stroke when I go to set the motor to TDC?

Thanks much!!

Steve

I adjusted my valves this past Friday and it wasn't too terribly difficult. The only issue I had was finding the "t" mark on the flywheel. There are several other marks that I found at first that I thought were the correct marks, they weren't and I adjusted the valves where the gap was too much. I turned the flywheel again and finally found the "t" mark and was able to adjust them to the proper gap.

I dreaded using my pull start to run the fly wheel fearing that it might not recoil back in, luckily I had sealed it and it recoiled back in with a little help. If you put some high temp rtv around the opening where the handle goes in you will keep 99% of the mud/water out of your recoil housing.

next time try putting it in 5th gear and rotating the rear wheel....worked for me better than the Zip cord!
