I Was looking for a better replacement gear for the water pump and came across mull engineering.They sell a billet water pump gear just wondering if any one has tried them and if they are any good.Thanks.

I have $6000.00 cash.Let me know as I'm bidding on almost the same one on ebay for $4500.00 but your looks a little cleaner so I'd be willing to spend a little extra for yours.

Fuck it I went with drag porting with 39mm carbs.I was only getting beat on the straight aways.We go at a quick pace all the time and trust me the top end is un-real.It comes on at about 4000 rpms instead of 3000.If I wanted bottom end that was predictable I would drive my yfz 450.

I just built another 421 cub and was wondering how 38 carbs (pwk)would be instead of my 35's.I mostly fly down back roads and try to out run my kids who are now going buy me.The jugs have clean up port job to them.I know I'll lose a little bit out of the hole but or will it drown .Thanks.

CAN YOU PLEASE LEAVE INFO TO BUY ONE OF YOUR KEAK DOWN TESTERS VERY INTERESTED. THANKS.

Thanks I installed the cel needles on the second clip.The plug is finally burning a golden brown instead of black.You would think it would run lean on the second clip ,but the hesitant is gone for now.Thanks once again.

I just bought a kit off of ebay from taiwan it came in in less then a week.Comes with everything even new choke plunger and seat and needle for $15.00.

I installed a set of keihin pwk 33 carbs with original needles.What needles are best for dunning and hillclimb.My elevation is 950 and temp is 70 degrees and cpi inframe pipes with hjr dune porting and v-force 3 reeds 21cc domes.Jetting is 155 main with 45 pilots needles on third clip 40:1 klots oil with 93 octane gas.It's almost perfect just a little hesitat from 1\4 to half throttle.I tried raising needle no effect.I was told to change needles just want to know what needles you guys recomend.Thanks again this site rocks.

Oh ya! It's Kevin at heerjugs sorry .

Call jeff at HEERJUGS racing he can set you up with the proper jets.My son banshee has almost the same set up as you and he's running 155 mains and 48 pilots airsrcrew at 1 1\2 turns out but confirm with Jeff.

I have the exact same up and I'm running keihin PWK 33 carbs and there perfect for trail riding just change your gearing.I installed 13\42 gearing and the CPI pipes rock.

If it was running O.K before you may have mixed up the plungers in the carbs.If you put the left in the right it will run like you have the choke on (smoke everywere)Check the toomey website it shows the correct possition.

Does anyone know who makes graphics kits for the fullbore plastic.Tried to use a kit for stock plastic no go..Please help thanks...

Hi, I was looking on the site for jetting tips for pwk 28 carbs.Jetting ranged from 145 mains to 280 mains.I just bought a set of pwk 28mm carbs.My pwk 28 carbs came with 150 mains and 50 pilots and a set of k&n pods.My elevation is 900 above sea level gas mixed at 32;1 klotzs r-50 oil. Motor is stock porting with 21cc cool head with fmf fatty pipes with v force 3 reeds.Will this jetting be OK for 70 degree weather.

Can you ship to Canada.

Try cascade

How much for pipes and silencers,thanks

I just installed a set of chetah jugs(68mm) and 4mm crank on my son's bike and the fmf fatty pipes I think are holding it back. CPI or Shearer or Rocket pipes.All types of riding from dune to trail to flat out flying.Thanks.

Once again Thanks,this site rocks.

Just wanted to know if this head is any good.

Only use forged wiseco pistons the cast will let you down.

The cutaway faces the back towards the airbox or it will feel like the choke is on.This is mistake #1 on the toomey trouble shouting guide

I just got a ADA cool head givin' to me with 21cc domes.Do I have to rejet for this head.Also when do you have to run race fuel the compression is at 145psi.Also are these heads any good.

Well the 30 pilots clean it up and 290 main letting her pull right to the end.The guy at vito's said that the pilot size they include in there kit is a starting point,but they don't included the smaller sizes pilots but give you 340 down to 290 mains.It's to bad that you can't just buy the needles.Oh! ya ,thanks for the answears to my questions this site rocks.
