Carbs can be great, if they are working nicely. However, when they go wrong... And that is one factor that EFI has a bit less. I enjoyed my Tiger 800 with injection. I have looked at the 900, but in my opinion it was so close to the 800 that I didn't really see the point for the extra expenses.

Having said that, I would prefer EFI and shaft drive...

Which means I will probably end up with something old and ratty again. ;)

Washers goes at the base of the spring (red arrow). I bought my leakdown tester at Harbor Freight but Amazon has them for $25. No compressor is a problem, you don't need a big one and you can find them used on FB marketplace pretty cheap.

While rebuilding the Mikunis is no picnic, once I did mine and then ran non-ethanol fuel, I've been trouble free. Fuel injection is probably great, but I am still impressed by what a carb can do when it is set up correctly. I did stop at a Triumph dealer to pick up a part, and I wouldn't feel bad about owning any of the new Tigers. I sat on all of them, and was quite surprised that I had no issues touching both feet to the ground. Probably never will afford one, but for me, I'd gladly trade fuel injection for shaft drive, as the chain and sprocket maintenance is more of a pain for me than the carbs.

I looked around at what else Sprint had and everything seemed comparable in price to what I could get online here or at the Triumph dealership nearby. Guy at the dealership gives me a bit of a discount too - probably out of pity as he's listened to me gripe about some things that had me held up for awhile. I look around for the French connection on the gasket you speak of.

I had some time last night and released all the cam caps and re-aligned the timing marks.

You mentioned before about putting some washers in for the spring. Figured I might try that while I'm waiting on the spring. Again just curious to see what corrected timing and spring does to my readings before going at the head.

Where would I put the washers in here?

I'm assuming at the red arrow in the picture below on the bolt essentially. But I guess you could also put some inside the tensioner unit at the green arrow?



A leak down test would be nice. Not crazy about the price of the units and I don't own a compressor. For some reason auto parts stores don't rent leak down testers. Might just build one though and get a compressor over the holidays.

Saw a fair amount of used heads available online should I need to go that route.

Tell me about your seat pad set-up, how long is it good for?

Sorry, I didn't realize you were Stateside.  I'd do a shopping list on needed items from Sprint to save on that shipping! My wife is from England so I had her bring stuff back to me when she was over this summer.
 I've heard their gaskets aren't that great and the (good) head gasket comes from someone in France.  I did order a bottom end gasket kit from them when I did my sprag clutch and the paper gaskets were a bit thin.
 The cam chain may be causing ticking, but it shouldn't affect compression that much. It may just be worn rings and not a head gasket problem.  A leak down test would be your best bet to diagnose the faults. Air hissing in carbs/exhaust is valves, hissing in crankcase is rings and hissing gurgling in radiator is head gasket.
 I'm down in South Carolin and got a ride in yesterday.  There were only less than 1500-2000 imported to the U.S. for the Gen 1 Hinkley Tigers during the 3 years they were here. 95-98.
P.S. I use Hermy's for stuff and they're good on price and shipping/service. They're in Pennsylvania and have been in business since the early 60's, family owned. Baxter's is also supposed to be good.  I ordered my Sprag clutch from Fowlers in Bristol UK because it was still cheaper with shipping than getting one over here.

Thanks for the further info. The spring should arrive in 2 weeks which is perfect because I'll be pretty busy in the meantime with other things. Going to do one thing at a time to avoid over spending here.

I'll see what a new spring and adjusted timing does to my compression and ticking and start to work further with maybe a new chain and then taking the head off.

The picture isn't the best. It is definitely off by at least a tooth, maybe more. - This would cause compression issues would it? I don't know if it accounts for the variance in compression between cylinder 1 and the others.

My oil has always been good in color and never had any milky look to it. Nevertheless, with the mileage I may do it anyway. Too cold here in Wisconsin to be riding anyway. I've got until May when I need to drive it out to Nevada.

My shims are all right around 2.7 with one being at 2.5. Otherwise the rest are in the 2.6-2.725 range

That spec 69mm is about what they all are once they have some miles.  A new spring or washer will make some difference.  The arrows will never line up exactly unless with a new cam chain due to stretch. Not sure that is a tooth off as it looks like just a few millimeters. You may consider a new chain at your mileage. The procedure would be the same as replacement. I'm not sure which shims you have in the valves but from factory I believe they are all in the 270 range? I can't remember exactly from what I've read here or elsewhere. 
  Other than the ticking, the low compression and possible head gasket failure would be a bigger concern.
 Here is a thread about valves service limits and remedies. Nnt that this is your probably but may be a consideration.  Mustang on this board was the Guru for many, Sadley he has passed away, but his knowledge lives on.

Some good news, I think. The cam tensioner spring is definitely below spec. It was at about 69mm when the spec is 73.7

Furthermore, it looks like timing is off. Picture below shows cams at TDC for cylinder 1. Arrows are supposed to be lined up and clearly aren't



Gonna order a new spring from Sprint.

What is the best way to go about adjusting the timing back into place?

Could anything have been damaged by this that I should look into?

Thanks for the info. I'll start with checking the chain tensioner and timing before proceeding with head removal.
