i just got done installing my hpr 14 t0 1 and hp3 cams.....
and i have to say im alittle disapointed... i cant tell the diff form stock
piston and cams..... it runs sweet, fired right up.. but thats it...... i rechecked the cam
timming its right on, i dont know, do i need more break-in time or do i need to
jet the tm 45 a little leaner?? i got a 160 main in it right know....
anybody got any ideas???????
thanx................

 

are you sure you are not running into preignition because that combo should make a ton of torque since those cams and 14-1 will build a lot of cylinder pressure. what happens when you close the choke some?

 

Rcoop has a good question.... What octane are you running and at what elevation?

 

close the choke??????? as far as fuel its race gas from the BP station down the road.. i think its 110, but not sure
its purple in color...... oh and i live in northern wisconsin.....

 

you close the choke a lil if it clears up your lean if it wets the plug your rich its a caveman way to get you started on your mixture. how does it pull rpm in gear? your best bet with that carb is to get ahold of jeff ross thebom on here. he would be able to get you on point quick, cause something is not right you should have a lot stronger torque curve.

 

dosnt pull well at all...... i road it up and down the ally alittle today today .. thats it...
with as much power as guys are talking about i should be able to pull the frount up,,
i cant......

 

are you running a snorkle tube or direct mount?

 

give jeff a call or email he will get back to you and get the carb figured out and hopefully thats the only problem and you will be carrying the front end in no time.

 

its a snorkle tube, with a twin-air power flow kit
and the tubes that went from under the gas tank
to the air box are gone....oh.. and air box lid removed to....
i dont know.. maybe im useing the wrong race fuel..
i just found a little book from the gas station that sells the race gas
and it says purple is 101 and has oxygen in it......
ill have to check tomarow........

 

I think your WAY lean on your MJ. I think with your set up it calls for a 175 main. What pipe ya runnin and what elevation? I "THINK" 160 is way lean. I might be wrong. Id try it. Also do a search on tm 45 jetting and you might get some specs on jetting.
