|arcore||will buy them, thanks, I hope they really are as they say, two other sets that I had bought years ago were at the limit of wear. The DL 14/16 does not need the camshaft positioning pin, it does not have a sensor, so it is something less to worry about.|

Brilliant idea with the false pin socket.. I only swapped exhaust cams and keeping the originals just in case.
What about these cams from germany, very low kms:

|arcore||SV to DL exchange, indeed if I put the trees directly it would not start, what I did was cut the Sv pin and put it in the DL position with a false socket. It works perfectly|

You need a cam indicator pin, which 05-07 SV1000s do not have on the rear intake cams. The biggest issue is that even if you have an 03/04 set of SV intake cams, they won’t work in the DL due to the cam indicator pin being in significantly different phase with the lobe. This will send incorrect timing info to ECU and bike will not run.
I have my machinist change the phase of the pins so I can swap into DL builds I work on.

|arcore||Knowing that it is a remarkable improvement increases my motivation. I'll try a home press and some waste trees if I can. I also consider the possibility of mounting some SV intake shafts in my Dl cut as DL to take advantage of the greater lift without losing power down, but it is difficult to find some used without excessive wear. Jumjum if your 03 trees are within values would you sell them? I already mounted SV trees in my previous DL and it is an improvement but power is lost in the lower zone and I don't want to do it.|

|jumjum||I would say the improvement is definitely noticeable. Its a cost free mod that makes your bike run better for a weekends work. I dont know how much tons of force it will take to press it off|

|arcore||Photography always helps, thank you. do you think a 10t cat would be enough or impossible? Is the improvement small or very noticeable?|

|jumjum||I used a hydraulic press with the cams at room temperature. It needed a good amount of force to press gear on/off. I ended up turning the gear clockwise about 3,25 degrees on both cams to get from 106/115 to the magic 106/108. Rode the bike yesterday after cam timing and could feel more punch at around 4-5k rpm|

Quick scan of the factory service manual, don't see mention of disassembly/reassembly best practice or use of fixative... will be interested to hear what others have found, without other guidelines I'd put the cam(s) in the freezer overnight and heat the gear(s) in the oven.

|arcore||Due to the pandemic that has displaced me from my usual garage, I have not yet been able to make the changes and tests that I wanted in my DL, so I am collecting data and I hope to be able to do it shortly. I was planning to move the draft with the crazy gear but jumjum kindly sent me your draft tool (thank you very much!) and then I consider looking for the exact draft directly in the trees by disassembling them, for this I am considering making a small homemade press exclusively for that. The question is whether I assemble and disassemble them simply by pressure or should I heat them, do I use grease or anaerobic fixative to assemble them or absolutely nothing?|

|arcore||Ok thank you|
|25th December 2020 12:33 PM|
|jumjum||arcore yes i can print one for you. just send me an email on [email protected] dot com|

|arcore||really brilliant jumjum. I do not have a 3D printer nor do I know any owner. would you sell me one?|
|25th December 2020 10:37 AM|
I made a little tool on my 3dprinter to help degreeing the 41t gear on the 05 exhaust cams. If anyone wants to give it a go design is on tinkercad. It worked great in my case..
