powrol 200x kit?

[willcamach]

my bike is in need of a rebuild and im wondering if anyone on here has ever done the premium kit by powrol to there x. in total it bumps displacment to 218cc ads a stroker crank and a # of other things. price = 735.00 for the parts not including labor and other parts that may be neccesary. i just bought the bike and rode it maybe 3 times before it started acting the hell up and so now im faced with the decision of upgrading to this kit which claims to give the 200x performance of a stock 250r their claim not mine....or doing a standard rebuild. any suggestions or experience with this would be nice and greatly appreciated please help as i am a total noob with two trikes i need to restore.

i think they mean an xr250r though. not a 2 stroker

[willcamach]

youre probably right about that.... lol but how powerful is that engine. and are these upgrades worth the almost 800 bucks or should i just do a cheapo standard build. and whats the average cost of a standard rebuild.

[350xsx]

a regular rebuild is about $200 give or take some depending on abor

i rebuilt my crank, then got a pro x connecting rod kit, weisco high compression piston, total gasket kit, and i honned my cylinder my self and it was 300 bucks. so he is right about 200 the crank rebuild was 100 bucks

so is the powroll kit overpriced it comes with a bore kit, hotter camshaft, springs and so forth and they require you to send in your old crank for them to do the stroker . according to them its a 50% increase in overall power. and they reccomend a ehuast system like a supertrapp and some other pipe. i already have a bassani on there i just want my trike to run good. and have decent power

I was lookin at it on the website. I think its worth it. Infact i wouldnt mind doing it to my 200X. Im sure it works its probably the same kit they had in the 80's and i doubt they would lie im sure its faster than a xr 250R like they say.

[vartiak15]

ide say go for it man. if i had the money i would of done it. got a pick of your trike. i wana see this basanni!

ull be right with a 400ex with that kit

[willcamach]

no pictures handy of the trike but i got the pipe off of ebay heres a pic of the pipe i will take pics of the trike and post them on here when i get a chance the trike is in my storage unit since i live in an apartment... im seriously thinking of doing this powroll thing if im gonna spend 300 bucks for a regular rebuild im game to go the extra mile and make this trike into a real quad killer....lol just thinking about my buddies face when he pulls out his suzuki lt250.... the few times we rode i was already neck and neck with him....

I'd have to see that one...

whats the advantage of a high compression piston kit. theres an option of 10.1 or 12.1 not sure what to go with

Higher compression means higher efficiency and therefore higher power. Infact, there's a simplified thermodynamic formula for the efficiency of IC engines and it's largely based off of compression ratio.

Higher compression generates more heat however. This brings up two points. One, mechanical components can only take so much heat so you are limited to a maximum value. Two, the higher heats will cause your fuel to ignite at inappropriate times and damage your motor. You want a fuel that burns slower for high compression engines. That fuel is one with a higher octane rating.

So, for your air cooled engine you'd be better to stick with 10/1 to keep overheating to a minimum and be able to run gas from your local station. If you go with the 12/1 piston you'll require more octane (race fuel) and perhaps your engine will overheat when ran hard for prolonged periods.

Just a thought.
If you're ready to move up in power, it's a thought.

350X's are VERY rideable, reliable and have the BIG power you want in stock form.

Again, no offense, just a thought.

Before you spend $700+ on modding a 200X, why not put that money toward the 350X?

Good Luck!

[Kintore]

I say, try it. That thing would have massive power, but do you want to spend 800? or do what MO350x said and put that towards the 350x. Just some food for thought

good luck and you can match your buddies Lt 250?
