start with a keihin and go from there.

I haven't ever seen any proof of which pipe is better for a worked engine. Just word of mouth mostly. No dyno graphs to show for. Maybe toomey is just fine who would know?

id like to here how jetting went for you on that carb. Crisp response without fouling plugs?

Every bike likes something different. Buy a few plugs and start richer until you get that color. Doing this takes time but still cheaper than a dyno tune and cant beat real world tuning anyways on a 2 stroke:)

you will struggle in sand with 20 inch 8 paddle hauler let alone anything bigger than 23. consider some gliders, you literally wont move with those lol

don't lighten them IMO. blasters already have little torque at low rpm with its small engine size then throw in the fact its a 2 stroke now you need all the torque you can get. it can work on dirt. I had an 8 oz lightened flywheel and while you might feel faster your not. just shifting quicker...

wow good stuff here. blasters mod for mod cant touch the bigger bikes. blasters get murdered on the sand especially by modded 400s and 450s. its kinda funny how badly too. and its excpected. just some teens thinking their cool with there super fast blasters. that said i like blasters. each bike...

ya the vitos would do you good but like said hard to come across now. ive had the cpi pipe and maybe it was just me but it didnt do well from stock bores to big bores, i feel like porting for that pipe needs to be done, but it kicked in so late in the band its not a fun ride and drops out of...

if you got an impact gun, i just go brrrrr a little good to go.

stock head anything over 120 will be just fine. youve got good compression, after 2-3 heat cycles the compression stops going up. i get them real hot then ride hard. i dont do heat cycles. make sure on the tester the treads are as long as the plug or it will read much lower if its not the...

exactly just a little bit of lt. use a torque wrench and torque properly. going by hand could be a reason they get loose.

make sure it is coming from there. if it is ya there's no gasket I believe its a liquid gasket you use. like blue permatex would work

right bends are fine, but lots of hype, i had a power pros a while back and it was ok, nothing more than a good left bend.

maybe a jet size or so, if its running clean i wouldnt worry about it.

do what everyone above said but keep your goals realistic. your not gonna pound the 4 strokes unless they are 300cc and under. the blasters top speed isn't close to a banshee or the bigger 4 strokes. you'll gear up a ton then lose lots of acceleration with that

we aren't talking big HP with just reeds. not sure what's up with the Guy bashing v3s. its about throttle response. get what you want but I'd get the v3s. and as fir the yfz comment. that's funny cause they are far more reliable and rebuilding isn't that much since the head and valvetrain...

back when I had the blasty I ran that pipe. easily the best low to mid pipe and best throttle response period. now quality wasn't the best and top end was flat but you can't have it all. all the other pipes have worse than stock low end even though noobs claim toomeys and power pros have lots...

ya the tors will do that lol. 155 sounds good for the main, 50 pilot seems fat, especially at your elevation. start with a 45 or 42, with air screw 1.5 turns out. whats the needle clip at? very important setting, find out where your needle clip is at, start at the 3rd or 4th clip...

if it was a real bad air leak it would rev high all the time, try cleaning the carb, check your pilot jet

the needle clip postion makes a HUGE difference, it will affect it right off idle to 3/4 thottle, it has the biggest play in how you bike runs, main jet is for wide open pretty much, also important, if its bogging or cutting out (not crackling and blowing smoke which would be rich, your...
