oxford grips question

Hi all,

I just bought a set of Oxford grips and my question is: if I put them onto my current bars, will I be able to get them back off when I order a new set of bars later on (several months away)??

The kit comes with super glue but I don't want to obviously destroy the heater grips to remove when I get new bars. Even without using glue, I need them to come off without damage!

thanks heaps.

If the choices are that limited stick it back together.
What does the piston look like where that scratch is in the cylinder.

One thing I noticed is the DR must have a big squish measurement.

I'd say that's way false. Even with a Race Tech gold valve installed, the Race Tech set up called for light (3 WT) oil on my shock. I seriously doubt the stock valving could even begin to handle heavy oil.

I know a lot of you DR guys think I should ge ta street bike, but I'll try to keep running this one (I just sold my larger street bike yesterday). As I wrote earlier, I really don't believe that the 90 to 95 MPH my speedo reads is really what I'm doing. At that speed I still have plenty of power to speed up to over an indicated 100, so this speedo is just way off if you are saying it doesn't have passing power past 85. I would say 80 to 85 is my real cruising speed. (Plan is to put a taller rear tire on, and a 16 tooth sprocket, by the end of this week - that should lower the RPMs a bit.) I am thinking about getting a steering damper for the twitchiness at those speeds, but I'll try new tires first. It really isn't bad enough that I'd slow down for it, but it seems like it would go into a tank-slapped if I fucked up enough.

So far body panels, the rear fender top-bolt, and the chain-guard are what I've found loose. Got lucky with the rear fender bolt since it somehow came all the way out, but stayed on the bike for +30 miles. It's obvious bolts were falling out for the previous owner, too, as there is a make-shift replacement on an exhaust cover that I can only assume fell out. I've only had the bike a few days, so while I can't say critical bolts are loose yet, if the few areas I have inspected or fooled around with are any indication then I'm going to have a lot loose.

Thanks Mongle, that top adjustable jig is just what I'm looking for. I should probably buy both for the allen-bolts that have round heads though.

And Harbor Freight has safety-wire pliers for cheap, so no big deal there. I don't need a professional set that resets itself since I'm not doing an entire aircraft.

I'll be doing a mix of Loctite and safety wire on the bike as I see fit. I understand the concept of how to safety wire (i.e. wiring to keep things tight), so it's not as if it would be pissing in the wind.

I ride north, instead of to Miami. My experience shows these commutes are much faster than those who ride from here, south, into the snarled traffic heading to the big city. Yeah, speeds are still high going south sometimes... and I-595 might as well be a NASCAR track going west in the mornings - actual bumper-to bumper traffic doing 80 or 83 MPH (measured with a car back when I used to do that route - you wouldn't catch me alive on the DR, or any bike, on that route at those times).

I love hearing about how Florida used to be (even crazier) back in the day - thanks for the stories guys. It's still sort of a third-world country, so ...

Yeah, I think you REALLY need a 16t countersprocket.

Old guys

My buddy who also rides a DR650 is 75, so a lot of you guys have many years of riding left I expect! :-) He outrides me (I had Polio when young so don't have much stamina for the rough stuff anymore but he does) He's a tough old guy! LOL!

I mostly just ride gravel roads now.

I'll bet there a quite a few older than my buddy and me.

How about it? Old guys speak up!

The 10W oil makes a great difference. It stops the rear pogo ing up after a bump. I found it not to hard at all.

I guess you could put new rings on and have the cyinder honed. My only concern would be blowby into the crank case putting too much contaminates into the oil. I think they make a special hone for the nikasil as it is very hard.

+1
It's not on par with a proper revalve but changing out the stock shock oil for 10w does make a significant improvement.
A proper revalve of the shock will be designed around using light oil to minimize fade due to loss of viscosity from heat.

I have wondered the same thing. I just went ahead and installed with the supplied "super glue". With alot of patience and gentle prying and probably compressed air, you should be able to break the bond to get them off. That throttle side is gonna be a pain to get off, and as with most throttle DR grip issues, just order up a new throttle tube cause I have a feeling it's gonna be destroyed upon removal, being plastic and all. Oh, and FYI, the aftermarket billet Moose throttle tubes that Pro Cycle sells will NOT work with Oxford Heaterz. The tube is way to big in diameter. For regular rubbery and more pliable grips this wouldn't be a big deal, but the Oxford grips are not flexible or expandable enough. Plus the billet throttle tube is knurled, so it makes it even more impossible for a smooth slide on application, especially due to the tight tolerances. Ask me how I now.

Yeah, I have one in the tool box and have used it for a lot of jobs, especially removing stickers and glue, but softening the carb boot escaped my thinking.

Yeah my wife always asks me what the hell I am doing with her hairdryer. I haven't yet found a use for the curling iron or hair straightener but I should think of one.

I'm about to buy a seat. Thinking about Seat Concepts. Can someone here who has one on their DR give an evaluation as to what they notice, if anything, when standing. I ride about 80% offroad and would like the Seat Concepts upgrade, but don't want to give up my stock seat for woods riding unless the seat concepts unit is workable for that application. If not, I'll just buy a complete seat (at double the cost) and keep the stock one for most rides.
