Hi All

Silly little question.

Long time reader, first time poster. I have an 07 Scram and I was going to put new 120 mains in. Do most people do rejetting with the carbs on or do you remove them? IF you do take them off do you take off the whole intake manifold (that looks easiest to me).

Thanks
Greg

Once you replace the factory phillips heads with allen bolts....you will not need to remove anything but the sidecovers.

I just rejetted my Thruxton. All changes can be made with the carbs on the bike. However, you may need to modify a screw driver if you need to replace primary jets. Main jets are easily accessable.

I just remove the jet holder and needle jet when changing on the bike.

Kinda whatever you're most comfortable with but I opted to leave the carbs in place and had no problems whatsoever. Just make sure that your screwdriver fits the slots in the jets. Make REALLY sure. You can do this by testing the fit on the new jets before you install them. You may have to shorten the handle to get at the primaries. Try to use a screwdriver that permits you to put a small adjustable wrench on the shaft. Then you can maintain upward pressure and pop the jet loose by turning the screwdriver with the wrench if you need to. And - - as mentioned - - get rid of those cheesy phillips head carb screws before they get you in trouble. You can get a complete set of stainless allen-head screws for $5.99 or so...

I have a Scrambler and I took the carbs off. I would recommend it the first time and maybe every time thereafter. You really can't get to the right carb with the exhaust there. You have to reach over from the left side of the bike. If you've got the tools, then you might give it a go, but I think you should be familiar with the chore before you try it.

You can try, but you will probably find that you strip at least one of the screws.

It is not difficult to remove the carbs - it took me 20 minutes.

Buy replacement screws first. After they are in, you definately don't need to remove the carbs.

I'd take the exhaust off rather than remove the carbs, unless the exhaust is a lot harder to remove than the Bonneville's.

I agree with everyone saying have screws bought ahead of time. I would leave them on the bike tho, it's not bad with an angle screwdriver, but you will strip 1 or more of the screws.

I used a small ratchet from True Value hardware. The kind you toss in the toolbox for "later". Sometime they do come in handy. It has several phillips head and torx head that you just fit in the adapter and into the ratchet. I did have to try 2 different phillips head to make sure I got one that fit really well, after all the warnings of stripped screws I've read here. I can see where that might happen. Did the top screws easily. Haven't done the bottoms to rejet, but intend on doing that on the bike also, now that I know I have a driver that will fit properly. As stated here before, not all phillips heads are the same, just make sure you have one that fits and no you'll have no problems. And replace those suckers with SST socket heads....M4
