Without fail every rider thought they were faster on the louder bikes but all were slower than the stock bikes.

Dang! Why didn't you let him throw himself under the bus? I wasn't going to make any assumptions. These are all reasons the exhaust system on my bike is still stock. A friend of mine is an athlete manager. Specifically for pro moto athletes. Because of this I have spoken to a bunch of pro mechanics and pro athletes. They constantly do research and testing on bikes and it still seems that they commonly go right back to the stock... If its not stock it seems that it's because something else isn't. I would call it a snowball effect. But with a completely stock motor..., it seems to always stay stock. Bikes, cars, etc these days are so electronically driven that those little changes just aren't going to make any difference. All in all my opinion of course. I also understand the significance of making something your own. So, if you like it, thats all that matters!
That reminds me, anyone heard from the guy that put Speed Triple cams in his bike? I'm curious of the outcome!!!

Any Tiger 800 owners in the Fredericksburg VA Area?

Which dealer do you use for service and why? Reason I'm asking.....relocating to that area next year and am contemplating purchasing a Tiger 800 in the near future. I presently use Hermys in Port Clinton PA for my BMWs and would rate them as one of the best around. I don't want to travel 250 mi. if I need to get the bike worked on.

Another related question..... being a half a&&ed shade tree mechanic how much service work would I be able to do on my own?

Thanks in advance.

Full bore usa m40-41 tires

Hey guys, these are really nice tires. I just mounted them last night, easy to do, balance up nice. The 150 rear assembly is a beast. Hard to get the thing back into the swingarm and lined up with the spacers and caliper. I'm used to 250-size dirtbikes. I just hope they perform as well as they look.

For my quick 6 mile commute they feel the same as the scorp trails, handling is neutral on road. Just a little buzz right at about 18mph on decel, otherwise I can't feel any difference. Smooth all the way to 75 for a very quick burst.

After next weekend I'll have about 1500 miles on them and will be in a better position to say, but so far I'm liking them...a lot!

I was strongly thinking K60's, but the mounting difficulties everybody complains about was holding me back. I have to be able to pop a tube out for repair while out on the open road. And they're expensive. The FB's are a hundred bucks less for a set, and if I can get 4-6K miles out of them I'll be thrilled. Then again, if the rear is toast at 2K I'll be trying something else.

Anyway, thanks for the plug. One day shipped from the distributor in Utah: http://kgmotorcycletires.com/full_bo..._m41_tires.htm

When I called them the kid that answered the phone didn't know anything except that they had them. He didn't know they came from the Shinko factory. Oh well, what can we expect??

As I sit here broken harted, I'm trying to figure out what happened. I was leaving work in the pouring rain (nothing new), I lost traction approaching a turn. I don't know if I psyched myself out or what. My Tiger slid into the outside curb. It hit parallel to the curb & threw me off. My leg hit the right mirror on the way to the grass. I feel extremely lucky. The only casualty is the rubber footpeg insert. I'm going to look for it when my wife gets home. My forks were twisted in the tree & the mirror I hit was loose. I now have a few tiny scratches in the tank plastic. Somehow, I managed to ride 10,800 miles without a tip over. The weird part is I have ABS & have gotten used to it in the rain. How did I loose traction? Yes, my tires were not warmed up. I had only traveled 300 yards in the pouring rain. However, I feel like ABS should have stopped me before I hit the curb. Maybe I was thinking about not hitting the curb instead of thinking about making the corner (if you know what I mean). Truly bizarre.
I guess they welded the shyte out of my right pass peg. It's still attached & no signs of stress.

I remember you saying something about a muffler, new map and the Tiger "wanting to go faster..." but a joke would be inappropriate right now.


The important thing is you are all right and the more important thing is the Tiger is all right.



and Dude, be careful out there. This thread needs you.

Sounds like you're in good shape and Tiger has some minor battle scars; that's about as good as a get off can turn out.
The way you described the incident it sounded like a traction issue. Are those Full Bores (Shinko copies) sketchy on the wet tarmac?

Some are sealing the spokes on the rear to run tubeless-easier roadside repair (usually).

Tools to get the frt. and/or rear wheel off. Tool or technique to break the bead.

I've got frt. tube; could be used in rear to get back to "town".

Slime (optional) for that slower leak- to get back to "town".

Pump/tire irons of choice.

Patience.....







I just purchased and used a set of Stubby tools. Much lighter, and I'll never use regular irons again.

I'm going to air the full bores down for now. The rear has stepped out a few times. I thought it was due to the muffler & arrow map. I've been using stock 36/42. The tires work way better then they should in dirt (aired down). Definately be careful on the Full Bore in the rain.
Next time I'm riding in the rain, I'll see what's up with these tires. Some emergency stops are forthcoming to test my ABS too.
Where I landed. I found my rubber peg cover.

I hear good things about the stubby tools- in fact the guy in the big brown truck should drop mine off this Friday...

Bummer Rob, glad you came out of it OK.

Could be a heat issue, maybe. It's been hot here in WNC, but I tend to think it's a bad batch of plastic/rubber that the indicator is made of.
Just finished my 8100-mile PA to AK ride. I still have one good indicator, and all my duct tape mods have held up for the last 3 weeks. I picked the bike up right in the middle of the nasty east coast heat wave, and I think the direct sun exposure made a bad plastic problem worse. Both front indicators cracked around the mounting ear...hard to believe they could be overtorqued enough to break with that brass spacer installed on the bolt. Just a weird occurrence all around. Good to hear your dealer is taking care of you. I haven't bothered to call mine yet...might just find an LED unit. I have handguard blinkers on my DRZ and I really like them, so I may go that route with improved guards.

Other than that, the bike performed beautifully. Rear battlewing is smoked. Off to mcsuperstore to shop tires..

@Bueller
Reduce the heat, not thermostatically controlled, from the cat which is considerable. There is no increase in noise I can detect or strange resonances. Most who have done it report a modest increase in torque. Will let you all know.

Well after 1st ride post re-assembly. The exhaust sounds ever so slightly deeper. Obviously the cat rattle is now gone & bike feels "different". Slightly more urgent would be how I can best describe it as. Oh and the right foot area is cooler to.
Costs:
My time
new header gaskets x3 = 10.15 - from UK
new header nuts x6 = 3.24 - from UK
Welding = €40
