Well Since this guy did a great job for me, I figured id post up what he has on his website. This guy does awesome work for a hell of a price. Anyway, heres some numbers to throw around....

 

Heres RB Racings web site..RB Racing

 

Hello all, I finally got the dyno up and running yesterday with a chance to try out the new Hoosier slicks on Yamaha rims. I tested my 358cc (.040 over) Yamaha Banshee using in-frame pipes, V-force reeds, 34mm PJ carbs on gas, stock cut head for race gas, and my full drag porting on stock cylinders.

 

Although the clutch was slipping we still managed to get 81.3 HP at the rear wheels. With a new clutch next week I think this motor will hit around 85 HP for sure!

 

Check out the dyno graph in the Dyno Run section of the site here.

 

Complete Banshee motor rebuilding. Includes new brand new complete crank, new main bearings, all new seals, new gaskets, new Wiseco Pro-lite pistons/rings, new piston pin bearings, fresh bore & hone, disassembly and reassembly labor for only $825.00

 

Lighten Flywheel $50

 

Mill and rechamber stock head $65

 

Case porting $50

 

Modify stator for timing advance $20

 

Port stock reed cages $40

 

Mill stock head $45

BASIC CLEANUP PORT $50 per cylinder

This porting will clean up all casting flaws and include porting of the intake and exhaust ports. This porting is an economical way to get good results for any type of riding.

 

MX/TRAIL PORT ($125 singles, $175 banshee's)

This porting will get you more than a seat of the pants power increase. Port heights, widths for all ports are modified and transfer inlet angles are all properly set for excellent low end and midrange power.

AGRESSIVE/DUNE PORT ($125 singles, $175 banshee's)

This porting will get you the absolute maximum power increase while still maintaining complete reliability and only a slight upward shift in the powerband. This is the most popular and best value porting we have. Complete alteration of all porting heights, widths, tranfer inlet and outlet angles are set-up using computer design software. Suggested for motors with pipes, reed mods and head work. Dollar for dollar you won't find a better port.

 

DRAG/FULL PORT ($200 singles, $325 banshee's)

Port widths and heights are maximized for peak power performance. Most cylinders will have additional intake ports, and/or boost ports added. Quads will require good pipe, head work, timing advance.

 

Sorry for the advertisement, But this is the best pricing/service ive seen! :beer: :thumbsup:

around october of last year i was going to have my cylinders ported, so i found rb i was kind of skeptical because of his cheap prices. i ended up doing alot of online research about this guy to see how people likes his work and see if maybe he just did a fluff and buff bullshit job. to date i have never heard a single complaint about his buisness! and that to me speaks volumes. all i got after reading lots of people talk about him on varous forums was nothing but positives. everyone seems to be impressed with his porting, and ESPICALLY impressed with the rediculous prices he charges. how can porting be so cheap? he must have porting down to a very quick science.

 

ultimately i decided against getting my cylinders ported. i cant justify tearing open a prefectly good running motor with factory new compression just to gain some power. i decided to wait untill i actually need a rebuild, then ill send my cylinders out to rb for some port work. you know what else, for $50 hell port youre cases. im going to get that done too when it finally comes time to do a rebuild.

RB rebuilt my Tri-Z motor.....he's knowledgable, fast, and a VERY nice guy. You'll be hard pressed to find someone saying anything negative about RB. I have a feeling he's going to be doing more and more people's work! I hope to get my Banshee in to him later this year.

 

(if you are reading this RB, I hope you enjoyed the beer :beer: )
