Just got a dynojet kit through for my VFR. One of the parts is glueing a shroud to the top of the needle jet.

Now it ought to be well de-greased (but I'll give it a blast of brake cleaner anyway) but I'm a bit wary of doing it given the utter chaos that could ensue if it came adrift and got into the engine.

One thing I'm also very aware of is that this is a 24 year old bike, presumably the glue in the kit is of a similar vintage.

Looks to be some sort of superglue, something which, in my experience, isn't all that super when it comes to a solid and reliable bond.

So. Stick with super glue? Or should I use epoxy?

Probably a silly question and you'd have told us but, is there any information regarding the "glue"? Any tradename or a clue to what it's made of?

If it's a cyanoacrylate, then it's pretty resistant to petrol. However, if you're not sure what the glue is specifically, I'd be asking the manufacturer.

The gullarm had shrouds in the kit, i just superglued them in,I'm sure the slide didn't rise enough for the shroud to become loose in the engine, it would just rattle around on the needle if it came loose.

It's a small tube of glue with the warning "Bonds skin and eyes in seconds" so I assume it's superglue. I've got some decent bearing fit grade cyanoacrylate at home.

@ No Blade. That's reassuring. Hopefully it's the same case with this.

It's just that I find superglue pretty brittle but if it's just stopping rotation rather than making sure my engine doesn't eat a small lump of brass, I'll be a lot happier. If they come adrift but stay in the carb, they can be reached through the airbox without taking the carbs off.

Chemical Metal, JB Weld would do the trick also.

JB Weld is completely fuel resistant once fully cured. That's what I would use. Mix it up, get it warm so it's runny and pop your part on.

Turns out I was worrying over nothing.

For one thing, it's like No Blade said, the needle never comes out far enough for it to escape.

For the other thing, it was a tight enough fit it needed to be drifted on (drift included in the kit) and is brass-on-brass so it'll expand at the same rate. Even without the glue (which I did use and was superglue) it's going nowhere.

All four carbs set up now, just need to fit them at the weekend.

My new JIS screwdrivers made the whole job a great degree less stressful and time consuming.

Completely forgot about having to drift them in, i still have the brass drift in my toolbox somewhere.

It's the restricted jap import one I got lumped with. A second gen VFR750. I fitted the carbs off my old 3rd Gen one and it's returning really shitty fuel consumption (as bad as my mates tuned off its nuts GSXR1100 oil boiler). Otherwise runs fine (if a bit down on power subjectively).

Already changed out the cams and CDI for full power ones so we're down to carbs.

I checked out the part numbers and the standard carbs differ between the UK and japanese spec mainly on main jet diameter and needle profile. Dynojet kit was the best and cheapest way to get a full set of full power jets and needles. Already got a K&N and Micron fitted anyway.

Had to drill out the lift holes, fit the above-mentioned main jet shroud, new needles, spacer and mains (Interestingly, smaller mains.).

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Bit the bullet and forked out for a set off ebay. Totally worth it.
