Yes I tried the stock petcock and like I said at about 1/8 it started acting up. I put the Pingle on and no problem I also got one for the 05 when I get it on the road.

OK, the reason the stocker cut you short at 1/8 is because the stand pipe is too tall without a pump, you can cut about a half inch off and it would have been just fine...but the pingle looks cool...........

Who looks at the petcock any way? Just as long as it doesn't stumble and stall is all I care about. BUT they aren't cheap ether.

Re:HSR 42 Information 4 Years, 4 Months ago  
Oh, good call Flashback, i will have to knock a half inch off of the stand pipe before shelling out for the new petcock. Even though stylish petcocks, i hear, are the new way to go

Im still a little staggered that with a larger carb the bike can still have a gravity feed fuel system. WHAT A BEAST!

I was definitely gearing up to port my stock manifold but i was told by a couple different riders out here that the rubberized surface crap tends to dry rot and when porting a manifold those abrasions can make them go bad even more quickly. That was why i wasnt hesitant... but knowing that the OEM man will fit the 42 carb ill just port my own and if it actually does crap out i can just pick one up from yamaha or hopefully find somebody elses old one...

Thanks, you guys rock!
Mike

Re:HSR 42 Information 4 Years, 4 Months ago  
Alright I have a shopping list if you guys would be so kind as to look it over with me. I dont really have an off season so i would like to have everything so i can smash this job as quickly as care permits.


HSR42 259.95
http://www.phatperformanceparts.com/Mikuni_HSR42mm_Carburetor_Standard_Finish_p/tm42-6.htm

Push Throttle cable 32.00
http://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Store_Code=ME&Product_Code=MAX_RS_42_CABLE_PUSH&Category_Code=ROADSTAR

Pull Throttle cable 32.00
http://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Store_Code=ME&Product_Code=MAX_RS_42_CABLE_PULL&Category_Code=ROADSTAR

That is the basic stuff.

Also on the list as per suggestion by all of you is:

Short Idle Screw 27.00
http://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Store_Code=ME&Product_Code=RS_MAXAIR_IDLE_KNOB&Category_Code=ROADSTAR

Choke Cable 68.00
http://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Store_Code=ME&Product_Code=RS_CHOKE_CABLE&Category_Code=ROADSTAR

Also im getting: ( the Jet kit is self explanatory and the Yost tube seems like a good idea since its like 50 bucks and im already in there )

Yost Pro uses Mikuni Jets 52.00
http://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Store_Code=ME&Product_Code=YOST_PRO_TUBE_M&Category_Code=NEW

Jet Kit 75.00
http://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Store_Code=ME&Product_Code=HRS_42_JETKIT&Category_Code=ROADSTAR

Currently the Bike has:

Maxair intake
http://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Store_Code=ME&Product_Code=MAXFLO_RS&Category_Code=ROADSTAR

Eventually i will get this: (though for now i will deal with the blinking light from lack of TPS)

Dyna performance ignition 269.00
http://www.maxairengineering.com/mm5/merchant.mvc?Screen=PROD&Store_Code=ME&Product_Code=DPI&Category_Code=ROADSTAR

I am primarily interested in performance tuning for now. So im going to stick with stock #97 and #70 needles and such. From what i understand those are in the stock carb so i will just move them over. then the jets will obviously be in the jet kit.

Im going to port my own stock manifold as per your suggestions and cut a half inch off the stand pipe of the petcock as per flashbacks suggestion.

ill just follow the instructions for the pump removal.

3/8 or 5/16 fuel line seems pretty easy to come by i just need to measure how much i need.

Ok, hopefully im not too far off. Please let me know how it looks.

Mike

The #97 refers to the needle. You can't use the needle from the 40 in the 42.

The main in the OEM carb is either a 165 or a 182.5; both mains are too large for the 42. The 42 comes with a 160 main; leave it in there. From the WOT test I've found the 60 OK.

Use 3/8" fuel line; 5/16" is too small and may be why some have starvation problems.
