650 internals anybody?
« on: November 17, 2011, 06:07:06 am »
Had a pretty decent weekend at last on my GeePeeZee, will report on that when i get the action pics, but it was not a great weekend for a fellow sohcer

this guy was running third-ish in the championship and decided to give it a last push by doing the last round near milan,
He lives in Lecce, about 700 miles down south at the tip of the boot....

well, sometimes better not push it... in 2nd qualifying motor went kaput with a bang, end of story.

he bought the bike ready to race but never opened up the engine to check before starting the season.  think he learned a lesson there, but it cant be funny going throw 3 days of driving, hundreds of euros in gas and lodging for this.

That said, he was lucky that the belly pan caught most of the oil before it reached the tire

There's always next season no?

Peek-a-boo.

Jokes aside, I feel for the guy. I know you ran with stock rods on your CB TG, but I have decided to upgrade in that dept. A few bucks of prevention.... There are still arguments against bellypans here, but it might have not only saved this guy crashing, but also a delay in racing while the track was cleaned.

I notice what looks like VM28's on that engine, carbs bored maybe?

We'll await your race report.

with the nr 4 cyl being really at the edge of the pan , i was surprised it still managed to collect most of the oil,

but certainly it proved the worth of our techs making it mandatory even if its not exactly period correct

dont think the builder was so sophisticated as to bore those 28's..... its an OK running bike but not a very fast one. actually my own race was saved because of this blow up as i lost one of the CR bowl plugs in the same qualifying session and it turned out that the VM28's have the same thread... would have been difficult to find a CR bowl plug on a saturday evening :)

the guy just gave me his!

gues he did not change the rod bolts after a rebuild

replace them with 13213-KVO-000  these are stronger and kost about 3 euro each  these are fitted in several honda types  [cbr 600 ]

take care when ordering you get the KVO types and not the 410

much scheaper than a new engine

i do have 650 internal spares  [for free]  crank - rods- valves- cil - gearbox

nice bit of info tuner!



will these bolts fit also on the 500's rods?

i think it will take Flavio sometime to get over the shock but I will tell him about your kind offer, he wil need new cases too...
