if i was to put the 240 kit, whick i'm most likeely to do, is there anything i should do before it , to prepare it, or that would help it, and where should i get it. vito's looks pretty nice.
I think i'm going to wait to get a bigger quad, i like the blaster cuz it's light ans so easy to whip arounf turns and over jumps.
oh, and will AMA let u race with a 240 kit, i'v herd that they won't with some 240 kits, and will it cost a lot to have a shop put it in?

 

anyone?

 

Call Eric at Trenga Racing. The number is (814) 231- 3884. Tell him Brandon the Sheetz guy told you to call.
Trenga knows their stuff when it comes to the blaster. I visited recently and saw their 240 kit first hand and it looks awesome. It's a completely redesigned jug and head. Give them a call and ask some questions about it. He can advise you on the best mods for your quad.

 

I talked to trenga a few years ago and they said they had CT build their 240 kits because it was cheaper for them. That new jug your seeing is probably CT's new aftermarket 240 cylinder and head. I'm with the other guys on this one. Don't waste your money!!! Take it from someone who has already done that! I'm stuck with my blaster, no one would ever want to pay me for what I have into it. You can check it out on my web page for an extensive mod list. Yes the 240 kits add a lot of bottom end, but I have heard from a lot of people that a well ported 200 performs about the same. I'm pretty sure the AMA blaster class is restricted to 200cc. A 240 kit is actually a 232cc because it uses a 72 mm piston. The largest you can go on the kit is 73 mm piston or 238.567cc .25*PI*bore^2*stroke all divided by 1000 = disp. in cc
(.25*3.14159*72^2*57)/1000 = 232cc If you do decide to buy a 240 kit have a well know engine builder build it for you or you will have problems later.

 

I understand your point completely. But when I was at Trenga he seemed pretty confident about their new topend. I don't know though. I agree that a nicely build 200cc could perform as well as the 240cc. There are so many variables that come into play when building an engine. I recently redid the topend of mine (still the stock bore) and installed a Weisco (stock bore) pro-lite piston and Trenga's new Aktive reeds with airbox vents. With those simple mods alone mine will outrun any stock blaster. It's amazing how such small changes can make such a big difference. I did this work myself for under $150. Some of these people ate putting $1000's of $'s into engines for one or two races and they are not very reliable. I think if CT made a 240 kit that was water cooled they could improve their reliability a bit more, but a stock engine is more reliable than any rebuilt or modded engine.

 

how much of a difference did your wiesco pro light piston make, i also had the active reeds
Well, if i didn't put the 240 in, what would you recomend to do to give it a lot more power

 

The Pro-Lite piston allows the engine to rev faster. It get into the powerband much faster and it's easier to keep your power up. When you get on the gas it just gets up and goes. The aktive reeds mode a huge difference in mine because my stock reeds were worn pretty bad. The edges were starting to fray. These mods will make your quad run much much better, but if you are looking for 240cc power then that's what you need to go for. You could get 240 cc power from a 200 cc engine, but it takes a lot of careful building and practice.

 

My best advice. If you want a 240 kit that bad, buy CT's new 240 kit with the aftermarket cylinder and head. It will cost you a little more money, but atleast when you do decide to buy a bigger quad you can take it off and put on your stock cylinder and sell the kit on ebay or somewhere else and get a lot of your money back. If you sell a 240 kit on the quad you won't get anything for it! Going with a lighter piston will decrease your rotational moment of inertia and after a long analysis it results in a slightly faster acceleration, had to do that in one of my classes.

 

Timewass,
If you look at Trenga's website you will see that they get their 240 kit from CT. I had my motor built thru Trenga and it is great. It is not a 240 kit but it does have a mild port job done. The mechanic that builds his motors is named Al. As far as crazyblasterrider is concerned, he asks the same questions about every 2 weeks to see if anyone will tell him anything different. For somebody that wants to get "big air" you need to upgrade your suspension and also get rid of the .125 wheels.

 

How about parctic riding/racing? Trust me, it helps. Aslo master the clutch even more.
