Vmax Cams & Venture Carbs
dingy replied to Reaney in NH's topic in Royal Star and Royal Star Tour Deluxe Tech Talk
1st gens also have 10.5:1 stock comp ratio. I am running 12.2:1 (about) on a 1300 block with VMax heads & cams, & block modifications. Mid range does have most power feel. Compression test should confirm or eliminate valve train leakage. Gary -
Overheating Revisited

A faulty boost sensor will keep timing from advancing as intended. Gary -
crankshaft question
dingy replied to quant55's topic in Venture and Venture Royale Tech Talk ('83 - '93)
Attached a picture from another thread regarding this block, if it is the same one. There is some significant damage under the near main bearing in picture. That may be cause noise you are hearing., Maybe not, but a good starting point. Post #15: http://www.venturerider.org/forum/showthread.php?p=822076#post822076 Gary -
jet kit with out drilling
dingy replied to speakerfritz's topic in Royal Star Venture Tech Talk ('99 - '13)
Drilling plugs out is primarily to adjust idle mixture. This is one of the basic steps most often taken well in advance of re-jetting. Shimming of needles is a separate issue. What are your expect to gain from re-jetting. Any air box or exhaust changes? Have you gotten a base line A/F reading to see what needs to be changed? Gary -

You have what Ignitech is supplying. Attached is a PDF file showing how I wire cables to use after market Sensor. I included some pictures of harness that has MAP wires added. I don't see a major difference between IAP & TPS settings other than the IAP settings are variable on left side of advance graph. The usage of either setting is dependent on an external sensor to vary a 0-5vdc signal in response to changing air pressure values. I have a TPS in place on Tweety, I just haven't hooked the Ignitech up to it. couple of pictures of what I did. 3D printed a modified spool in the throttle junction block to drive TPS. Gary -

I tried the setup shown in attached pictures. I used a 5 port Vacu-tite fitting to tie the 4 sync ports together. The 5th port ran to a 1 1/2" PVC pipe with a cap on both ends. I tried several lengths of the chamber and the shortest possible worked to smooth out pulses while still not inducing to much lag. Not using it now, just running vacuum from #2 port. Gary -
New intake boots - torque?
dingy replied to Jinksy4's topic in Royal Star Venture Tech Talk ('99 - '13)
If it's looks like you could get a long drill down in there to put a helicoil in with. The tap drill to put a 6mm helicoil in is 1/4", closest American drill. This is an easy drill to find in an extended length. The helicoil uses 7mm tap to prepare for coil. As far as the tap drill for the existing holes being drilled through into oil pocket, this was knowledge of 1st gens, I don't know if the 2nd gens have same issue. Gary -
Time for second gear repair

I'm a happy camper with my Dano starter clutch. Tweety was starting to have issues. Higher compression in motor was accelerating failure. Picture of reworked rotor I got back from Dan attached. Also picture of stock starter clutch assy., removed from rotor. Rather puny in comparison. Gary -
Vmax Cam install help... Please?

Pictures attached indicating timing holes in VMax camshafts. #1 is both cams side by side #2 is exhaust cam small hole #3 is exhaust cam large hole #4 is intake cam small hole #5 is intake cam large hole (180 deg from small hole+/-) Gary -
Wayne, There is "14" cast into master reservoir near banjo bolt port on the 9/16" units. 14mm roughly equals 9/16" (.5511") 1/2" masters had "1/2" cast on them. Don't know why fractions once & metric on later unit. Gary
-
Since you delinked the brakes, it would be helpful if you put a 9/16" master on at this time. That will give you more volume to drive the doubled caliper piston volume. MKII's had 9/16" brake master's. MKI's were 1/2". Gary

Mystery part...What is this pin?
dingy replied to yamagrl's topic in Venture and Venture Royale Tech Talk ('83 - '93)
It is not a bearing retainer pin, they are far smaller than size of found pin. There are no needle bearings in block near this size. It is a shifter pin. Gary -
Yes. Gary

Picture of upgrade shift segment attached. You do not need the plate at top left, old one is fine. Picture of parts break down attached & link to page. http://www.partzilla.com/parts/search/Yamaha/Motorcycle/2003/ROYAL+STAR+MIDNIGHT+VENTURE+%28Onyx%29+-+XVZ1300TFSR/SHIFT+CAM+FORK/parts.html The shift segment pins will be hardened steel, not easy to cut at all. All needed pins are about $10. Shift segment is $33.32 Gary -
Some pictures of the Hybrid as it progresses. Heel toe shifter replaced with a 1st gen pedal. Head light is dual projector units with HID unit on high beam. 2nd gen master cylinders may not work on the 1st gen bars due to angle of reservoir body, 1st gens are angled so top is parallel to ground. 2nd gens are at a quite an angle. I can install 1st gen masters if 2nd gens don't work out. Front shock spring adjustable pre-load spacers installed. 1st gen rear rotor, 320mm floating, mated to 2nd gen caliper. Front end is entirely 1st gen, except calipers, these are from YZF750 Yamaha 1997. 6 piston units. Gary

Aftermarket TCI available!
dingy replied to tvking63's topic in Venture and Venture Royale Tech Talk ('83 - '93)
You also have third option of Manual setting. In attached picture, I drew an arrow to the 3 settings that are added when Manual dwell is selected. I have not worked with this setting though. It would seem that shortening the dwell time would help. Gary -

The Ignitech can use either the stock Venture sensor or an aftermarket sensor. A one bar sensor is best option. I include an aftermarket unit that is wired into adapter cable. There were a couple of issues that drove the new MAP sensor. 1st, the stock sensor is a 12v output. Ignitech said 12v would be OK with TCI, which is 5V based input/outputs. 2nd, by supplying a new MAP, there was a known good replacement for the stock sensor, which has been known to have failed. I have been using TPS setting on units I sell. MKI, MKII and VMax settings are similar for MAP settings, no substantial differences. Gary
