Std coils or aftermarket? Does the misfire occur 2 or 3 days in a row whatever CDI is fitted? Maybe coil breakdown through heat is a possibility - one pair or cylinders or across all 4? Mind you running any engine at 2 million revs is gonna lead to issues LOL! But 2000 is fairly low for electrics to give up - maybe it is gunge in a carb - idle / pilot circuits?

That is a pretty damn good lookin' motorsickle - put it to bed for the winter, fresh for springtime.

Ah well - the wife will have to go then - distraction, costs money to run, needs servicing now and then.

You said complete stock system - hence the comment!

.................which will weigh more than the bike LOL!

Ha Ha Ha - perfect for reliving the moment when your engine melted in the comfort of an old arm chair with a mug o' tea! A dyno is definitely the place for WOT tuning turbo's IMO!

Nice, Tidy solution as I hate the ones hanging below or above the headlights !

Wrong angles, wrong diameter, wrong height - anything else............it'll be wrong!

Agreed - a blow thro only needs slightly bigger MJ's than for NA. And very surprised if std miki's are holding 3 psi fuel pressure - most leak / pass fuel anything approaching 2psi LOL! And the the fuckin back end of the bike strapped on the dyno - that was plain dangerous!

Tidy - and could work as chain oiler as well - bonus!

Not to familiar with Jap market GSX 250 but the top picture is the head breather, but bottom picture - not known as the bigger family do not have crankcase breathers at all, let alone in that location! The head should have a hose that vents into the airbox in front of the carbs so fumes are drawn into the motor to be burnt.

So what if the swingarm isn't centered or parallel to the front wheel? The parallel bars method really is the quickest and correct way to get wheels in line THEN you worry about chain alignment. Vizman for POTUS LOL!

Maybe not yet ............................but you're gonna need MORE brakes at the front - trust me!

Mine hasn't!

The whole front fairing is on its own sub-loom with a black 9? pin plug & socket near the head stock - i'd start here and test forward and back.

Don't believe GSXR liners will go to 1246 - you need Blandit barrels for that, GSXR would be waaaaay too thin IMO!

I've not known anyone go through the brass plug which is just a plug for the bored gallery behind - save the aggro and just double line from the RHS, job done.......... or single line from gallery to a tee piece to equal length hoses up to cam links...... if you are OCD!

Where are you first off as Melling's are in the States and seem to be great for typical V8 truck motors so you'll be paying bespoke fee's and freight and import duty! There are US bike performance shops who'll sell you ready finished sleeves off the shelf or of course if in the UK there are importers for the US bike parts or UK manufacturers of sleeves/liners. But if its a shoestring build then just get another blandit barrel, get it bored to 81mm & rebuild - this is assuming you have 81mm pistons already. If you are spending £££ then I believe you can bore the cases out to take 90mm o/d liners and 86mm o/d pistons but going that big causes other issues that need to be addressed - like the blandit block will be daftly thin!

Teflon lined hoses for coolers is unwarranted - not enough pressure to worry them .......Rubber with braid cover is perfect and more flexible considering their size............................and cheaper!

Agree - definitely two lines, each connected into the 'manifold' between the cams - disconnect the line from the cam cover otherwise the good pressurised oil will force itself into the cooling circuit due to the lower pressure. You need the two lines as there is no direct oil connection between the two sides of the head . Whilst restricted oil flow could be achieved with some jets - I personally wouldn't bother as the cam bearing clearances will restrict the flow and keep pressure high up to the point of use - the GSXR oil pump system produces some 50% more pressure / flow than it needs with excess bled off back to the sump, so even with excess oil going up to the head / cams via worn cam bearings the pump will make up the shortfall.

But real question is, why no oil up barrels............or did you block off the gallery at the base of the barrels?

Just your description is wrong! 'Dry blocking' has no oil flowing through the block AT ALL - the galleries at the bottom are blocked off and an external oil line is used from the main gallery to the cams directly. You have an 'auxillary' feed from the low pressure / high flow cooling gallery. Does beg the question why you had no oil from the cases though.........if you don't have an external feed! And that connection on its own won't provide the oil pressure required!

When you say 'dry blocked' it - you mean no oil up the studs and so have a line or two from crankcase to head? Pictures would be useful. Hate to say it but if the cam is gone the head will be trolleyed as well - ali cam bearings always lose to steel!

Eh ! ! ! - can't have it both ways - either the same OR bigger!

Hasn't the Powerscreen got a Helical primary whereas the Blandit is straight cut?
