Thanks Digger, so the torque is halfway between damn tight and friggin tight
I found a torque bit size table and measured screws with calipers and I also came up with #40

Is there some trick to shimming these engines?

I tore it down for the 12k service on the 13th of this month. The intakes were good but the exhausts were all off (tight). Most ranging around .227 - .290 clearance.

So I bought the appropriate shims and put it back together. I measured everything before buttoning it up and found that I was still off. It all came apart again and new shims were installed. Once again I double checked everything and found that I was still off. Things were getting closer but certainly not where they should have been, and still, way under spec (tight).

This is the formula I've been using to get the needed shim size.

A= (B-C) + D

A. New shim thickness
B. Recorded valve clearance
C. Specified valve clearance (.325- .375) (exhaust 800 XC)
D. Old shim thickness

I have pulled these cams out and re-re-re-re-re shimmed this bitch no less than 8 times since the 13th and am ready to throw a match on the POS and call my insurance agent.

I started it yesterday and all I heard was valve clatter. It wasn't the hydraulic tensioner I heard, it was valves. I measured everything an hour ago and everything was still around .250 -.330 +/- (nothing loose and most still too tight). WTF?!

I'm not a bad mechanic but this thing is making a complete fool outta me. What am I doing wrong?

Sounds like you're using inches instead of mm, so I'm at a loss with your numbers (which is odd coming from a yank that builds boats) but shims come in .05mm increments. Seems your math is correct. I just figure what the next size up or down is, added or subtracted to the shim that's in there to give me the right clearance based on what my feeler gauge is saying. If the clerance is .10mm and I need 15 and the one that is in there is marked 235 then I get a 230.

Are you sure you got the cam chain tensioner set right? They can be tricky.
Are you getting different clearance figures when you reinstall the cams?
Are you measuring in the right place?

I've never had to change more than a size up or down to get the proper clearance. But I haven't done the tiger either.

If you want more clearance you need a thinner shim.

Wouldn't it be A = D - (C - B)?

Using the above example:

D = 235
C = 15
B = 10
235 - 5 = 230
A = 230

Revs at 90 mph

New to this thread. I am considering buying a Tiger 800 both for commuting and touring and was wondering what kind of revs the engine reaches while doing 90 mph. I currently have a GS and a Varadero and both seem to hang around 5000 revs at 90 mph which leaves the engine note at low pitch.

With stock gearing you'll be well over 6,000rpm. For me at 6k I'm doing 133km/h or so (approx 83mph)

This is one of the interesting differences in the Tiger vs F800GS, and one of distinction. I just finished reading the comparo in Motorcyclist Mag that also highlighted this, so I'll share my 2c after a half hour test ride on the GS.

The Tiger engine with its 3 cylinders is a beautifully revving engine with a 9,800RPM redline and makes more power higher in the range. The GS was "industrial" in the linear manner it provided power. It wasn't impressive, but functional. It's said to be an advantage on the trail but I wasn't able to test. If you spend any time at all on the road, the Tiger will be more fun.

The GS got very vibratious over 6000RPM and felt like you were pushing it beyond its comfort zone. It was fine when it was in the sweet spot. Because you never wanted to push the GS it always seems to get better gas mileage.

The Tiger is just way too much fun to wwWWWAAAAAAAAAAA!!! up in the range. And it's silky smooth the whole time. It was like a completely different machine once I got past the break in period and could use the throttle and rest of the range. My cheeks were sore from that ride because I was grinning so much...

Yea, the GS may be slightly better off road, but the Tiger, to me, was better if you were 50/50 because you could have fun on the trails, but still have fun on street rides rather than just riding around. All you need to wrestle with is what tires...

Has anyone update their XC ABS to tune 20769?

If so, are there any noticeable changes?

All measurements are in mm.

I'm certain my math is right but the feeler gauge says I'm wrong. Apparently I'm not getting accurate measurements with the feeler gauge.

The cam chain tensioner is set right. Measurements are taken while the lobe is strait up and the bucket is resting against the cams base circle.

I'm getting different measurements when I re-install the cams, but that's because I have new/different shims in place when the cams go back in. Unfortunately these numbers do not always reflect the changes that should have occurred with the new shim. Again, I believe I am not getting an accurate/consistent reading with the feeler gauge. Bending the gauge to squeeze it into place is throwing my accuracy waaaay off.

For those that have shimmed an XC, what type of feeler gauge did you use? How did you get accurate measurements?

First, get a narrow set of feeler gauges that are bent or bend them. Use 'go, no-go' sizes.

Are you putting a micrometer on the shim or reading the etched number? My indy will mic them and then exchange what I had for what I need. Sometimes the number can get worn enough to be difficult to read.
Are you sure the cam bearings are getting properly seated?

I just went through this with my XC, but thankfully all were within spec. The exhaust were all heading towards the tight end so I'll be swapping shims next time no doubt.

The Tiger was quite a bit easier than my wife's Street Triple, even though they're basically the same the Street Triple was packaged tighter and checking the inside exhausts were a bitch. I had bought several sets of feeler gauges, bent some, broke some and swore lots.

I had ordered these feeler gauges but they hadn't come in yet, so I get to try them on the Street Triple next...



Offset Tappet Feeler Gauge Set

Back to the Tiger, I just used my straight feeler gauges and as mentioned the go, no-go method. Start with the smallest clearance, does it slide in easily? Move up to the next, and carry on till you can't insert the larger/largest feeler. It's definitely a "feel" thing, the gauge should slide in there with a "bit" of force, but not have to be "forced". You can jam a too thick gauge in there and say that's the clearance, but that's not the "right" clearance. I had feeler gauge drag described to me as "should be like pulling scotch tape off a roll".

My valves were:
Exhaust (0.325 - 0.375)
1,2,3,4,5,6
0.33,0.33,0.33,0.33,0.33,0.33

Intake (0.10 - 0.20)
1,2,3,4,5,6
0.15,0.12,0.12,0.12,0.16,0.16

At 90 mph you are worried about the revs? This is what will make or break a Tiger for you? Must be a Malta thing…

I have no experience with checking valves, so I'm going to have to make an appointment at my dealer for the 12K.

My plan was to take most everything off and ride it the 4 miles to the dealer. Then, I would have them just check the valves and electronically sync the throttle bodies and make sure the latest map is on there. Is this a good plan? What else needs to be done?

Also, right now I'm running a LV carbon pipe with the Arrow map. My mileage is not great (38-42mpg), but I'm also running K60s and a 15T front sprocket. I regularly ride around 72-75 on the highway. Should I put on the stock pipe, have them remap it to the latest stock map and then switch the pipes when back home?

I have read it is ok to run LV or Arrow pipe with stock tune to keep mileage up, but what about power difference?
