Usually I do a compression check on the bench immediately after building an engine to make sure I put it together right.  Usually the initial readings are pretty close to what they will be after the rings seat, but not always.  The readings you posted are similar to what I have seen on some engines.  Usually mine are over 200 psi and fairly uniform among the different cylinders after running on the dyno.  It depends on the cam.  A hot cam lowers the cranking compression a little bit. 

My typical practice is to use Union 76 10-40 basic quality mineral oil with Red Line break in additive at first.  Racing oils are used after that.

The horsepower will increase when the rings seat.  It is only a few horsepower more for the little bike motors I work with.

Your readings are similar among the cylinders - this is good.  Some compression gages read high or low.  Try another gage.  Check your intake cam timing if the readings do not rise to the expected levels.

All sorted now! Dyno results are to say the least not what I had hoped for but I have learnt loads on this build and will be on the salt having a great time this forthcoming speedweek,I wont be breaking any records but it aint all about that and the next project is already bubbling away in the deep dark recesses of my head.

Bummer Oz, might have to make room for a bigger NO2 bottle.

Like you said, you will have a good time, how long until the bikes leave?

It is good to see that your motor is sorted and you are headed over here for speedweek.  Do not feel bad about not getting all the horsepower you want at the beginning.  This LSR is difficult.  It takes lots of fiddling with different things to get the power.

All done and dusted so just gave it a try on the ozco patent transport skid and it fits lovely only 5 weeks till it ships and 10 weeks till we fly out cant wait!!!







See you on the salt.

Ozco-branded stuff looks fine from here. cheers  Are the springs compressed as much as they look - or is the bike that low?  I'm wondering if you'll suffer some long-term effects of having the shocks and springs at full squish for the weeks it'll take from when you button it up to when it's back on the ground.

We'll see you on the salt!

They are down just over half way, And the bike is very low about 3" at the lowest point I reckon the springs will be ok its been strapped on the bike lift for over a year like that with no noticeable problems......I hope they will be ok Damm dont want to start worrying about more stuff now! cool

Back in the early '70s I helped to introduce the ANKRA strap system to the MC dealers in Wisconsin.  A big help for long-distance travel is to place a block of soft wood (pine) or a firm block of extruded foam beneath the motor/frame and then compress the bike with straps.  This wil prevent the bounce-effect when traveling as well as assure the suspension will only be compressed by no more than half.  Another way of doing this is to insert a length of 2 x 4 between the lower tree and the front tire.  If you use a modern roll-over front-wheel chock, the most important straps are placed near the rear suspension and pull FORWARD at an outward angle.  I have hauled dozens of bikes (sometimes 8 or 9 in a trailer) from Utah to Wisconsin to Alabama and have yet to lose one.

Looking good Oz

Looks like the frame does more than just transport with the extra bits sticking up each end?

Im not too sure what month, we get them a bit late over here.

it was in the front of the magazine in the bottom corner with a bit of a story about how the guys from the UK were going to the states to race at Bonneville and a photo of Oz's bike with a few others.
