2001 jug fit on 99 ??

Recommended Posts

Checking if a 01 jug will fit on a 99? The piston,crank and rod are the same but is the jug different between those years ?

I'm needing a jug for a 99 to make a big bore kit.

yes. albeit there are probably minor porting changes. I know no1clyde intermingles all sorts of years and pcs to make his big bores.

I will wok fine but you need the 01 powervalve too.Also the center powervalve needs to be cut to clear the bigger bore piston. You should also put a 94-98 1'st gear in it too as the 99-01 had a very high 1'st gear. Good luck.

Yeah its for a KX sorry.Thanks clyde.I've been trying to get ahold of Eric gorr but cant seem to get ahold of him.So the big bore might be out and keep it stock.

I'm using that same combination 01 250 cylinder on my 99. the 01 cylinder doesn't have as much overrev or topend compared the 99 cylinder, Another consideration if you're going to use the 01 you'll need the 01 reed block as Kawasaki narrowed it in 2001. FYI the 01 cylinder has a smaller main exhaust port but larger sub exhaust ports and smaller intake.

If you use a FMF gnarly pipe the difference between them is hardly noticeable, Still a fun bike to ride.. the 98 ignition swap is usable but I like the 99 ignition better for the broader power with nice overrun capability :thumbsup:

Thanks ! I found a 01 block so I thought I would use that for a big bore kit.But the way it looks I will just go back to stock cant get ahold of the big bore people and now its making more problems than helping out so might leave it stock.

i have an 01 kx250 and i was told to put a 98 jug on it because tht was the fastest most powerful older kx engine so it should all fit together perfectly i believe good luck

what about the 98 ignition on a 94-95? will it fit and also give it better over-rev?

maybe 98 ignition is a good update as the 98 are renown for having the sweetest powerband back in the day.. but to run like a 98 you need more than the ignition.

Add the Carb, reeds and pipe. that's a load of parts needed.... perhaps cheaper if you wanted more top end....use a FMF fatty or PC pipe

my bike already has an flying machine factory fatty pipe and spark arrestor. i got the bike in a basket basicly. i already put a complete bottom end in it and going to over bore the top end if i win the wiseco piston on ebay. i also plan to add v force 3 reeds and run the stock carb. i was going to port and polish the cylinder before i sent it out for a replate and cut the head but with gas prices, i may hold off. it needs alot of work to bring her back to riding condition. need a frame, certain nuts and bolts, every suspension bearing except steering, levers, bar, plastic, tires....but its coming along. plus i dont have to money to go out and buy a new or used running bike that just needs gas, so im doing what i can to piece this bike together on a limited budget.
