Re: Engine Masters 2019

Everybody must be thrashing away, its pretty quiet around here. Trying to hit the dyno one last time Friday. Thought my journey came to an end last week. Got it short blocked, should have a new oil pickup Tuesday, hopefully with a flat flange this time.

Re: Engine Masters 2019

Got over the first hump today. Ran the motor in and made a couple of pulls. Pk Tq and Hp look good but the bottom end needs a little work. Its somewhere to start :) .

Re: Engine Masters 2019

I have a couple pieces to try that friends lent me, but nothing like the big dreams I had at the start of this deal. The time spent on the little things can sure make the days go by.

Re: Engine Masters 2019

Its crunch time! Anyone makin' headway out there. I've been battling some things but starting to get though it. Hope to have the engine running in the next couple of days. Hope I'm not the only one who hasn't gotten fired up yet. :|

Re: Need recommendation on drag radial

MT should have a crossover for the drag radial size wise. Set up is something else. Tire pressure will have to go up. I think we were running 12.0psi with bias ply, ended up around 15.5psi with drag radials. The other thing is they don't grow much so you rpm will go up at the end of the quarter I th...

Sadly Bruce Crower passed away

Founder of Crower Cams and Equipment Company, Bruce Crower passed away at age 89 few days ago. I spent a few years working with his son Dan at Crower Motorports out of Bruces shop. He was a very nice man, and probably one of the best manual machinists I've ever seen. He was a wealth of knowledge and...

Re: Engine Masters 2019

Our project is coming good. The block is pretty ready to go. Most of the hard parts are in. The valve train has probably given me the most fits. If someone knows of an LS style exhaust valve that does not have a 25* degree tulip I'm all ears. Right now its a mix match- o-rama.

Re: Engine Masters 2019

Has anyone got a confirmation on wether or not the heat cross over in the exhaust ports can be filled?

Re: For you with bike carb knowledge

If the bike is at speed and has any kind of air going by the heads it will stay cool enough. 325F-350F CHT is fairly common. I have a fair bit of experience with air cooled engines. Air and Oil and Timing are going to be your main methods of cooling the engine. Running the motor slightly fat is one ...

Re: For you with bike carb knowledge

Jetting changes with load. Engine Brake dyno's dont shown this when your testing at a given rpm/sec. Your spread is large which means your tune needs work. 12.0 is too fat, and 10.5 is something else.. Lean the bike down 3 jets straight away and tune it in high gear. Once you get high gear close 12....
