I have been at this for a little bit have seen some tips on upgrading the engines from drilling out jets to the next level exhaust. I was wondering what works not like the nitrous that's just dump. i hear alot on the boost bottles and the reed valves post your best upgrades here!

Remove the head gasket...

That's the second time I have seen you type that 26

How does that work?
do you need to do any prep work to prevent blow by?

 

[Houseworth_t]

ya what joab said. thats to increase the pressure that builds in the chamber right? since there would be a smaller gap

Try it, it's only 4 nuts. Works great for me...

 

[bairdco]

just make sure both surfaces are completely flat and that the piston doesn't hit...

do you just eyeball it or use clay? how about polishing the exhaust port and the combustion chamber? and last has anybody used methanol [big jets]

I'm always touting the billet intake-
you just missed the President's sale at Bikeberry where it was going for just over ten dollars-
getting the carb close up to the cylinder seems to make all the difference in carburetion, and for the most modest cost.
The NT 66 carb with a 66 motor also helps performance, but not so drastic and at more cost.
not a motor upgrade, but the more narrow the tire, the better the roll
and a 36 sprocket works well, on the road at least
