Hey guys I came across this tomberlin crossfire 150r and I was wanting to get this thing upgraded a little bit but wasn't sure what and how?? So I figure I would start at the Carb I guess? Bigger jets?? Then air and exhaust of course....so any help about what carb jets or air filter and exhaust ideas would be appreiciated!!! Thanks!

I just did the same thing but I out a little more into it

So far I've purchased
Uni & redneck filter
26mm carb &intake
Port and polish
A12 cam
11g sliders
Red main spring
39t sprocket
And a new belt.

I have 25's in the rear

So I'll let you know how she works when I get it back together

Gman has a good list there. The Carb is probably overkill and the 25s will be too tall still but should def have more power. Start with a uni rejet do the variator and clutch mods. Don't worry about a coil or Cdi.

Ok...uni...and this is where I'm getting confused..I can put bigger jets in the carb I got or get a bigger carb all together???

Uni is a type of filter. And the redneck intake is a shower poke or some type of tube that will fit. On the carb. As for the carb if yours is operational just re jet it. Mine was toast so I bought the bigger one

Ok I got the air filter and all but what I can't find is the bigger jets...I really dnt know what size I have...I guess I need to know that but I would assume its stock but I ain't sure what that would be..oh and y'all please bare with me because I can do the work I like tinker on stuff but the knowledge about it all and the terminology is what I lack...obviously lol but I do thank y'all for taking your time to help out....just please explain in details thanks!
