I've ran searches and talked to some people in the chat here on the connection and havent found a single person that has a Pro-X 310 kit on their 85-86R. It makes me wonder, why not? I've spoken with 344pv about his bike, but i fear it isnt comparable to his bike at all. My goal is to run decent at the drags and hill with a stock swing arm and I think a 350 is just too much for a stock length arm. Does anyone have any experience here with a 85-86R with a 310 kit? how did it pull compared to stock or ported 250 cylinder? who ported it and what mods did it have? Your info is greatly appreciated.

 

I dont have a 310 kit (keep getting outbid by snipers) but I can speak for a GOOD port n polish job on a stock 250R. A GOOD top end port for drag racing n such, is way to much for a stock swingarm. You will need to go at least a +4 for a good port n polish. So before you dish out the money for a 310 kit, look into a port n polish from a good person. I know of one that can port a stock bore R that will hang with everyone but the all out dragsters.. I can give you his name and email if you pm me.

 

Mine went (in a quad) 4.9 .......... But why not spend 50 extra bucks and get a 330??

 

I have a lot of trouble with my stock arm on my 86 in the sand. Buddy of mine has one that he did for a guy and the guy never picked it up so i might buy that but i dont know how much longer it is. I want a +2 BTW. only basis i have for my R is running R's with similiar bolt ons and no porting - usually a good 4-6 bike lengths and im still pulling away, at the hill.


i want the 310 so i can get used to tuning it and how the bike is going to react to the torque. isnt ESR's bolt on 330 just a bored 310? i already have a good price on a 310 from CT. i wouldnt mind a 350PV some day, but I dont have the kind of money to be dropping on that and suspension mods as of yet.

 

have you talked to alan at CT to see what he recommends when do you pick up your 310

 

when i have the money. [img]i/expressions/face-icon-small-smile.gif[/img] i just sold some parts and am still saving. reason its taking so long is im planning on buying a 38 air striker, new pipe and ext filter kit, at the same time. im still estimating middle of sept but at worst i think it might be the middle of august, but either way i have untill halloween for the season to officially start up.

ill start asking CT questions when im closer to having the money. right now im just soaking in all the info i can.

have you ever thought of running a 370 or possibly just alky on your 344?

 

i was thinking of turning mine into a hill bike, if the the new honda 450R is any good i will get one of those for a dunner. my 4" over will be for sale then. i thought about a 370 but it would be on gas for sure. my 344PV is getting reported right now.

 

my exact thoughts!!! granted my R is great to ride in the dunes id much rather have it for racing purposes mostly. if honda does release the quad, u can expect to see me on one shortly as well.

 

think ahead and get the swing arm you will need.

 

Hey Guys , Here's your lucky Day ...I've created a steering stabilizer for the 85-86 ATC 250r. This baby works "awesome". In fact it downright eliminates the high speed wobble in the whoops , need I go on about the "fatigue" factor on hard rides. If you are interested in some pic's . I've got 5 home designed , shop produced units to part with.....
