I ordered my Christmas present (from my wife) yesterday. A set of Maxis RAZR 20/10/9's for the rear, 21/7/10's for the front, on Douglas .190 Rims. I wanted to get the ITP Holeshots, but when I placed the order from RMAtv, they were out of stock. Anyway, I'm sure this set will be an awesome improvement over the stock rims/wheels I'm currently running, plus, the RAZR tires look super trick!!!(IMHO) I told my wife to wrap them up and I won't open them till Christmas.

Since I went to a 20" rear tires,,,will I need to change the sprockets/chain? Thanks, and Cheers. Dave.

 

my favorite mod was hetrick porting




and i would go to a 14 tooth since u went to 20"

 

Namura +5 hp piston kit. They have them on E-Bay for $95.00 w/shipping. They work very good. Pipes I like Pro and bills.

 

1badblaster,,,

Tell me more about the porting. What kind of performance gains did you get? How much did it cost? Is it compatible withe the Toomey B-1/Boyesen Rad valve setup? Thanks, Dave.

 

Harw,,,does the kit use a stock bore, or is it a sleeved kit? 5HP gain for 95 bucks sounds almost too good to be true???

 

The pistons come in std.,.020,.040,.060,.080 over size. They bore in to your stock jug then change the jetting to around 260 and you are ready to go.

 

yes the porting is compatible with the toomey pipe

it will cost you about $300

huge gains from stock, won't be able to tell it is the same bike in any performance aspect

i went from a ct ported 240kit to the 240cc with hetrick porting and that was even a huge difference

 

the spacers are good and the front wheels can be filped inside out and will make the front wider too. I think after the pipe, you have to take off the air box lid, it makes a mega difference!

 

With all that power if you got porting youd probably want to get new suspension,you can get awesome suspension for only 700$ front and rear!

 

You mentioned Bill's Pipes...what size jet did you use?
