Crazycarts crap. #2

[crazycart]

Thanks man. Of course, they need work, (pistons) but i have 2 250r top ends ready to go. Then ill save up for a TRX330 piston (for the 300 kit) and porting by flotek.

Cool man, You don't want to do the port work yourself?

 

[crazycart]

Well, there is a huge difference between our 'cleaning up the ports' and professional port work. Its a science. Porting makes HUGE gains when the 'porter' actually knows what has to be done for the riding style, and has the experience. There's more than just polishing and opening up holes. Denny at Flotek knows what hes doing. Check out the 300R drag bike, ported by flotek

Banshees are twin cylinder liquid cooled 350's, 250r/300r is a single cyl air cooled.

Yeah, I know the difference between just cleaning it up and actual port work. I've seen it done many times at Polar Motorsport's of Carelton Place, Ontario. Hes one of the best known people for performance clutching for snowmobiles and Junior Dragsters. He also builds snowmobile racing engines and you should of seen a liquid 440 on the dyno. It was only on one cylinder for now but holy crap did that thing SCREAM around 10.5 rpm. I think it pulled 48 HP on one cylinder at 10.5. Shaking the dyno room pretty darn good!

 

[crazycart]

Why was he running only 1 cylinder? Surprises me that it wound out that high on 1 slug? Newer liquid 440's pull 110 hp stock!

 

[jr dragster T]

They test and tune one cylinder at a time. Hes been making changes and changes and more changes for the past 4 months. I'm not allowed to tell anyone his R&D. These motors are for competition use and in that class there also restricted to 32 mm carbs. They have made secret parts to work around the small carb.

One of the 250R's...played in the mud. Bassani pipe, Mikuni TMX Flatlside carb, 200x front end...Front end climbs to the sky in all 5! One of them is soon to receive the 300 bigbore....

 

[jr dragster T]

Nice, Currently I am rebuilding the top end of a 2005 CR85R

 

[crazycart]

I've done CR80's and KTM 85's...basically the same thing..Is that engine power valved? If so..be careful not to mess up the linkage adjustment.

 

[jr dragster T]

No, It is not equipped with power valves.

 

[crazycart]

Got a hondaline piston for the 300 kit. Will be installed in the next few days...Lets see if ill be able to keep the front end down with 12/44 gearing and the stock swinger.....

 

[crazycart]

Yeah..getting a newer YZ80 for 100$

 

[crazycart]

Got the YZ80 and started building my ATC300R Ice racer.....

300cc Big bore
Bassani Pipe & Silencer
TMX36 Mikuni Flatslide
UNI filter
155 PSI

Should run fairly well

 

[jr dragster T]

IDK, mine didn't have all the hoses on it. Bought it at haydays for 5 bucks. They are a BEOTCH to take the slide off.

x1000.

How in the world do you even get it off the cable?

 

[crazycart]

This helped me:

Otherwise good carb, going from an old round slide to this carb there was a tremendous increase in response.
