? on big bore kits

[Mack_10]

I am a newbie to the pit bike world and was wondering any differences, gripes, or complaints ( or positives for that matter) between the 70cc, 82cc, and the 88cc kits for the crf/xr's. Thanks! ?

theres not much difference between all the 88 bore kits out there, except once you start looking at the heads. theres probably not a huge difference between the 81/88 kits in terms of power. from 70 to 88 there would be quite a difference though. reliability wise they would all be just as reliable as the stock honda top end. hondatrailbikes.com has the best prices and from what everyones says great customer service as well, although i have never delt with them, good luck ?

Any of the kits will add a good bit of power over stock. All depends what you want to spend. With any of them make sure you add the high volume oil pump while you have everything apart. Cheap insurance.

In the long run a 88 kit is the best buy. (the TB is the cheapest, they are awsome parts). One good thing about a 88 is, if you ever want more power there are many, many heads out there to choose from. Not many heads out there will work with a 82cc big bore kit.

Actually none will work with a 82, you cant find a domed piston for them.

thanks fellas, now my second ? is whats the diff between the TB 88 R-stage kit, 88 s-stage/ superhead kit and the 88 regular head kit??? me corn-fuzed ?

TB makes a kit with a head and a kit with out a head. The aftermarket heads have bigger valves and better/bigger ports that flow better and make a little more power.

The takewaga R stage is takewagas 88 with an aftermarket head

The takwaga 88 s stage is a takewaga 88 kit that uses the stock head.

Let us know how much money you want to spend and how much more power you want. If you want a lot more power and have a pretty meand little bike the TB 88 with head is the best bang for you buck ($400 for the head, cam, cylinder, pison, carb, etc). The Kitaco 88 SE head is the best kit out there for performance (but that is over a grand with out a carb)

If you want to just wake your bike up a little bit the TB 88 stock head is the the best way to go ($275 for the cylinder, piston, cam, carb, etc)

Once again, let us know how much you want to spend, what kinda of power you are looking for and what kind of riding you are going to be doing. We will steer you in the right derection.

Race and the other fellas you guys are awsome! Thanks for all the info, i will get back in a couple days and let you know about the other options......... cant thank you guys enhough for the help! ???

[Mack_10]

well i ended up buying a 03 xr 50 with tb 88 kit, tb pipe, applied front end, i shock, and a host of other mods for 1400, its in awsome shape to! But the guy told me he did not put the high flow oil pump on it...... funny cuz i was talking to my buddy at the yamaha dealer today and another worker said hey i got one........ 10 bucks! so i grabbed it and ran........... now to install the damn thing! Thanks for all the help!

[Jetster220]

Ohhhh, man you gotta take the whole topend off and the clutch to install that, you know that right.

[Mack_10]

ya i printed out thier instruction for it, the ? is now for someone to doit, cuz time is something i do not have.............. any ideas...... i live in long beach ca.

[nappers]

If I were you, I wouldn't worry about the high volume oil pump for just an 88kit. If you had the head, I'd say bite the bullet and do it. But, just for a regular 88kit, I wouldn't. It's up to you though.

[KMM181rmz]

i dont think its that hard to do to cuz i put a tb 88cc cylinder and head on my bike with the instructions and was easy. it says that a trained technicion is suppose to do it but i had no problem. ?

[RaceMX84]

If its a stock head 88 i wouldnt waste my time putting the oil pump on. If its a 88 with race head it would be worth doing

skip4343, what kinda head is it? Are you saying a ported 50 head cause yea a stock 50 head works lol.

[KMM181rmz]

Mack 10, were did you get the instructions for it. they would probably help me out a little. thanks

[RaceMX84]
